Unpacking Your 2019 Nissan Frontier’s Truck Bed Dimensions

Before you even begin to browse truck toppers, the most critical step is to thoroughly understand the exact dimensions of your 2019 Nissan Frontier’s truck bed. Nissan offered the Frontier in various configurations, and the bed length is the primary factor dictating topper compatibility. Failing to get these measurements right is a common mistake that can lead to costly returns and frustration.

The 2019 Nissan Frontier typically came with two main bed length options, depending on the cab configuration:

The Shorter Bed: Primarily with Crew Cab (CC) Models

Many 2019 Nissan Frontier Crew Cab models feature a shorter truck bed, often referred to as a "short bed." This configuration is popular among those who prioritize passenger space and find a shorter bed sufficient for their hauling needs. It offers a good balance between maneuverability and cargo capacity.

• Approximate Length: This bed typically measures around 59.5 inches (approximately 5 feet) from the bulkhead to the tailgate. It’s crucial to measure along the top rail for the most accurate dimension for a topper.
• Approximate Width: The width usually measures around 58.8 inches at the bulkhead (cab end) and tapers slightly to about 57.2 inches at the tailgate. The width between the wheel wells is significantly narrower, roughly 44.4 inches.
• Approximate Depth: From the top of the bed rail down to the bed floor, the depth is generally about 18 inches. This measurement helps determine the internal height of the topper you might need for specific cargo.

The Longer Bed: Often with King Cab (KC) Models

The King Cab (or Extended Cab) versions of the 2019 Nissan Frontier were frequently paired with a longer truck bed, commonly known as the "long bed." This option is favored by individuals and businesses requiring extra cargo space for longer items, tools, or camping gear. The extended length provides significant versatility.

• Approximate Length: This longer bed typically measures around 73.3 inches (approximately 6 feet) from the bulkhead to the tailgate. Again, precise measurement along the top bed rail is paramount for topper fitting.
• Approximate Width: Similar to the short bed, the width is around 58.8 inches at the bulkhead and about 57.2 inches at the tailgate. The space between the wheel wells remains consistent at roughly 44.4 inches.
• Approximate Depth: The bed depth for the long bed configuration is also approximately 18 inches, consistent with the short bed. The difference lies solely in the length.

Pro Tip from Us: Always double-check your specific truck’s dimensions. While these figures are standard, minor variations can occur due to manufacturing tolerances or aftermarket modifications. Never rely solely on model year or cab type; take physical measurements.

The Crucial Measurement Process: How to Ensure a Perfect Fit

Accurate measurements are the bedrock of a successful truck topper purchase. Don’t skip this step or eyeball it. Based on my experience, many first-time buyers underestimate the importance of precise measurements, leading to ill-fitting toppers that either don’t seal properly or look mismatched.

Here’s a step-by-step guide to measuring your 2019 Nissan Frontier’s truck bed for a topper:

1. Measure the Length (Inside Bed Rail):

   • Use a sturdy tape measure, preferably a metal one that won’t sag.
   • Measure from the inside edge of the front bed rail (closest to the cab) to the inside edge of the rear bed rail (closest to the tailgate).
   • Ensure the tape measure is flat and taut along the rail. This is the primary length measurement a topper manufacturer will use.
   • Perform this measurement on both the driver’s and passenger’s sides to check for any discrepancies, taking the average or confirming consistency.

2. Measure the Width (Inside Bed Rail):

   • Measure the inside width from the driver’s side bed rail to the passenger’s side bed rail at three points: near the cab, in the middle of the bed, and near the tailgate.
   • This ensures you capture any slight tapering of the bed rails. Record all three measurements. Topper manufacturers typically account for slight tapers, but having these figures helps.

3. Measure the Width (Outside Bed Rail):

   • While not always strictly necessary for a standard topper, measuring the outside width from the outer edge of the driver’s side rail to the outer edge of the passenger’s side rail (again, at three points) can be useful for certain custom-fit toppers or if you’re exploring unique designs. This confirms the overall footprint.

4. Measure the Cab Height Clearance:

   • This is often overlooked but vital for ensuring a level and aesthetically pleasing fit.
   • Measure the height from the top of your truck’s bed rail to the highest point of your cab’s roof. This will help determine if a standard height topper will sit flush or if you need a "cab-high" or "cab-over" design.
   • Some toppers are designed to sit slightly above the cab, while others aim for a perfectly flush line. Knowing this measurement helps prevent an awkward appearance.

Common Mistakes to Avoid:

• Measuring the bed floor instead of the top rails: Toppers sit on the rails, so rail-to-rail measurements are essential.
• Using a flimsy tape measure: This can lead to inaccurate readings due to sagging.
• Measuring only once: Always measure at least twice, and ideally three times, to confirm accuracy.
• Not accounting for existing bed liners or rail caps: These can slightly alter dimensions. If you have them, measure with them in place.

Decoding Truck Topper Sizing Conventions

Manufacturers typically don’t list toppers by "59.5 inches" or "73.3 inches." Instead, they use specific conventions tied to vehicle models. Understanding these will simplify your search for a 2019 Nissan Frontier truck topper.

Year, Make, and Model Specificity

The most common and accurate way manufacturers categorize toppers is by year, make, and model. For your 2019 Nissan Frontier, you’ll be looking for toppers specifically designed for a "2019 Nissan Frontier." This ensures the topper’s base precisely matches the contours of your truck’s bed rails, including any subtle curves or angles.

• Precision Fit: Toppers designed for your specific year, make, and model will have the correct length, width, and even the curvature of the cab-side bulkhead to seal properly. They also align perfectly with the tailgate.
• Cab-to-Topper Alignment: These toppers are engineered to match the cab height and styling, creating a cohesive look rather than an afterthought.

"Short Bed" vs. "Long Bed" Terminology

While manufacturers specify year, make, and model, they will also differentiate between the bed lengths using terms like "short bed" and "long bed."

• Nissan Frontier Short Bed: This refers to the approximate 5-foot bed found on many Crew Cab models. When searching, you’ll look for "2019 Nissan Frontier Crew Cab Short Bed Topper."
• Nissan Frontier Long Bed: This refers to the approximate 6-foot bed, often found on King Cab models. Your search would be "2019 Nissan Frontier King Cab Long Bed Topper."

It’s crucial to confirm which bed length your 2019 Frontier has before ordering, even if you think you know. This is where your precise measurements become invaluable, confirming whether you have the "short" or "long" version for a 2019 Frontier.

Types of Truck Toppers Suitable for Your 2019 Nissan Frontier

The market offers a diverse range of truck toppers, each with unique materials, features, and price points. Your choice will depend heavily on your intended use, budget, and aesthetic preferences.

1. Aluminum Toppers

Aluminum toppers are the workhorses of the topper world. They are typically the most economical and rugged option, making them a popular choice for contractors, tradespeople, or those on a tighter budget who prioritize functionality over sleek looks.

• Durability and Weight: Aluminum toppers are lightweight yet incredibly durable, resisting dents and corrosion. Their lighter weight means less impact on your fuel economy.
• Customization: They often come with options for ladder racks, toolboxes, and various door configurations, making them highly versatile for work applications.
• Appearance: While functional, they generally have a more utilitarian appearance. They are usually painted white, black, or left in their natural aluminum finish.

2. Fiberglass Toppers

Fiberglass toppers are the most popular choice for personal use due to their sleek appearance and customization options. They offer a more integrated, automotive look that can be color-matched to your 2019 Nissan Frontier’s paint.

• Aesthetics: Fiberglass toppers are molded to fit the contours of your truck perfectly, often aligning seamlessly with the cab’s lines. They can be painted to match your truck’s factory color, giving it a unified look.
• Features: These toppers come with a wide array of features, including tinted windows, interior lighting, carpeted headliners, power locks, roof racks, and various door styles (lift-up, side access).
• Security and Weather Protection: They provide excellent security and superior weather protection for your cargo, making them ideal for camping, hauling sensitive equipment, or general storage.

3. High-Rise and Mid-Rise Toppers

These are variations, often made from fiberglass or aluminum, designed to offer extra internal cargo space.

• High-Rise Toppers: These toppers feature a raised roofline that provides significantly more vertical storage space than a standard cab-high topper. They are excellent for hauling taller items, or for those who want more headroom for camping inside the bed.
• Mid-Rise Toppers: A compromise between cab-high and high-rise, these offer a modest increase in internal height, often rising a few inches above the cab. They provide a bit more room without the dramatic appearance of a full high-rise.

4. Commercial/Work Toppers

Specifically designed for tradespeople and commercial applications, these toppers prioritize functionality, security, and durability. They can be made from heavy-duty aluminum or reinforced fiberglass.

• Heavy-Duty Construction: Built to withstand rigorous use, they often feature reinforced roofs for heavy ladder racks and robust locking mechanisms.
• Storage Solutions: Integrated toolboxes, shelving units, and interior lighting are common features, designed to organize and secure tools and equipment.
• Access: Many commercial toppers offer multiple side access doors in addition to the rear door, allowing easy retrieval of items without having to climb into the truck bed.

From a practical standpoint, I’ve found that for most personal users of a 2019 Nissan Frontier looking for a blend of style, security, and functionality, a fiberglass cab-high or mid-rise topper is often the best choice. For those using their Frontier primarily for work or needing maximum utility, a durable aluminum or commercial-grade fiberglass topper is usually superior.

Key Considerations When Choosing a Topper for Your 2019 Nissan Frontier

Beyond bed size and type, several other factors should influence your final decision. Taking these into account will help you select a topper that truly meets your needs and budget.

1. Material (Revisited)

• Fiberglass: Offers superior aesthetics, paint matching, and often better insulation. It’s generally more expensive but provides a premium look and feel.
• Aluminum: More rugged, lighter weight, and typically less expensive. Ideal for heavy-duty use where aesthetics are secondary.
• ABS Plastic/Composite: Less common for full toppers but sometimes used for specialized covers. Generally lighter and more impact-resistant than fiberglass, but with fewer customization options.

2. Features and Accessories

Consider what features are important to you. Do you need windows? How do you want them to open (sliding, tilt-out, fixed)?

• Windows: Tinted windows offer privacy and UV protection. Sliding windows with screens are great for ventilation, especially if you plan to camp.
• Locks: Keyed locks are standard, but power locks (integrated with your truck’s central locking system) offer convenience and enhanced security.
• Interior Lighting: Battery-powered LED lights or wired lights (connected to your truck’s electrical system) are crucial for visibility in the bed.
• Roof Racks: If you plan to carry bikes, kayaks, or extra gear, a topper with a reinforced roof and integrated tracks for a roof rack system is a must.
• Headliner: A carpeted headliner can help with insulation, reduce condensation, and give the interior a finished look.
• Ventilation: Vented windows or a vent system can prevent heat buildup, which is important for pets or certain cargo.

3. Budget

Truck toppers range widely in price, from a few hundred dollars for a basic used aluminum model to several thousand for a fully loaded, color-matched fiberglass topper.

• Entry-Level (Aluminum): Expect to pay $800 – $1,500 for new, basic models.
• Mid-Range (Fiberglass Cab-High): Prices typically fall between $1,800 – $3,000, depending on features and paint match.
• High-End (Custom Fiberglass, Commercial): These can easily exceed $3,000, especially with advanced features, reinforced construction, or specialized configurations.

Remember to factor in installation costs if you’re not doing it yourself.

4. Intended Use

Your primary use case for the topper is perhaps the biggest determinant.

• Camping/Recreation: Look for features like screened windows, interior lighting, carpeted headliners, and potentially a high-rise design for more headroom.
• Work/Tools: Prioritize durability, security, integrated storage (toolboxes, shelving), and possibly side access doors. Aluminum or commercial fiberglass are strong contenders.
• General Storage/Protection: A standard cab-high fiberglass topper often suffices, offering good security and weather protection for groceries, luggage, or sporting equipment.

5. Color Matching

For fiberglass toppers, achieving a perfect color match to your 2019 Nissan Frontier is possible. Most manufacturers use the truck’s paint code to ensure the topper blends seamlessly with your vehicle’s existing finish. This enhances the overall aesthetic and makes the topper look like an original part of the truck.

6. Weight and Fuel Economy

While toppers add weight, modern designs, especially fiberglass and aluminum, are engineered to be as light as possible.

• Impact on MPG: A topper will slightly increase the overall weight of your truck, which can have a minor impact on fuel economy. However, some studies suggest that a properly designed topper can actually improve aerodynamics by smoothing airflow over the bed, potentially offsetting some of the weight penalty.
• Suspension: For heavier commercial toppers or if you frequently carry heavy loads, consider whether your Frontier’s suspension might benefit from an upgrade (e.g., helper springs or air springs) to maintain a level stance.

Installation: What to Expect When Fitting Your Topper

Once you’ve chosen the perfect topper for your 2019 Nissan Frontier, the next step is installation. You generally have two options: professional installation or a DIY approach.

Professional Installation

• Expertise: Most truck topper dealers offer professional installation services. This is highly recommended, especially for fiberglass toppers that require precise alignment and wiring for interior lights or power locks.
• Warranty: Professional installation often comes with a warranty on the work, giving you peace of mind.
• Proper Sealing: Professionals ensure the topper is correctly sealed to prevent water leaks and is securely clamped to the bed rails. They also handle the electrical connections for lights and locks.
• Time: Installation typically takes 1-2 hours, depending on the complexity of the topper and its features.

DIY Installation

For those comfortable with tools and basic wiring, installing a topper yourself is possible, particularly for simpler aluminum models.

• Tools Required: You’ll typically need wrenches, a drill (for wiring access), silicone sealant, and possibly a second person to help lift the topper onto the truck bed.
• Basic Steps:
  1. Clean Bed Rails: Ensure the bed rails are clean and free of debris for a good seal.
  2. Apply Sealant/Gasket: Place the provided foam or rubber gasket along the top of your bed rails. This creates a waterproof seal.
  3. Lift Topper: Carefully lift the topper onto the bed rails, ensuring it’s centered and aligned with the cab.
  4. Clamp Securely: Use the provided clamps to secure the topper to the bed rails. Distribute the clamps evenly and tighten them firmly, but avoid overtightening, which can damage the rails or the topper.
  5. Wiring (if applicable): Connect any wiring for interior lights, third brake lights, or power locks to your truck’s electrical system. This usually involves tapping into existing wires (e.g., taillight wiring).
  6. Test: Check all features and ensure the topper is sealed and secure.

Common Mistakes to Avoid During Installation:

• Overtightening clamps: This can warp the bed rails or crack the fiberglass of the topper. Tighten until snug, then give an extra half-turn.
• Skipping the gasket/sealant: This is the primary cause of leaks. Always use the recommended sealing material.
• Improper wiring: Incorrect electrical connections can cause blown fuses or electrical issues. If unsure, consult a professional.

Maintenance Tips for Your Truck Topper

Proper maintenance will extend the life of your truck topper and keep it looking great on your 2019 Nissan Frontier.

• Regular Cleaning: Wash your topper regularly with automotive soap and water, just as you would wash your truck. This prevents dirt and grime buildup that can degrade the finish.
• Waxing/Polishing: For fiberglass toppers, waxing or polishing a few times a year will protect the gel coat from UV damage and maintain its shine, especially if it’s color-matched.
• Check Seals and Clamps: Periodically inspect the seals around windows, doors, and the base of the topper for any signs of wear or damage. Replace worn seals promptly to prevent leaks. Also, check the clamps securing the topper to the bed rails and tighten them if they’ve loosened over time.
• Lubricate Hinges and Locks: Apply a silicone-based lubricant to hinges, gas struts, and lock mechanisms every few months to ensure smooth operation and prevent rust.
• Inspect Wiring: If your topper has electrical components, occasionally check the wiring connections for corrosion or damage.
• Winter Care: In colder climates, ensure seals are clean before freezing temperatures set in to prevent doors from sticking. Avoid using harsh ice scrapers on windows.

Frequently Asked Questions (FAQs) About 2019 Nissan Frontier Truck Toppers

Q1: Can I use a topper from another truck model on my 2019 Nissan Frontier?

A: Generally, no. Truck toppers are highly specific to the year, make, and model of the truck, including the exact bed length and the contours of the bed rails and cab. A topper from another brand or even a different generation of the Nissan Frontier is highly unlikely to fit properly, resulting in gaps, leaks, and a poor aesthetic.

Q2: Does adding a truck topper affect my 2019 Nissan Frontier’s fuel economy?

A: The impact on fuel economy is usually minimal and can vary. While a topper adds weight, which can slightly reduce MPG, some studies suggest that a well-designed, aerodynamic topper can actually improve fuel efficiency by reducing drag over the open truck bed. The overall effect depends on the topper’s design, your driving habits, and the weight of your cargo.

Q3: How long do truck toppers typically last?

A: With proper care and maintenance, a high-quality fiberglass or aluminum truck topper can last for 10-20 years, often outliving the truck itself. The lifespan depends on the quality of materials, exposure to harsh weather, and how well it’s maintained.

Q4: Are truck toppers completely waterproof?

A: A properly installed truck topper should be highly water-resistant and protect your cargo from most rain and snow. However, no truck bed system is ever 100% "waterproof" due to the dynamic nature of truck beds and varying seals. Minor seepage might occur in extreme weather conditions, especially near the tailgate. Regular inspection of seals and gaskets helps maintain optimal water resistance.

Q5: Can I remove the topper easily if I need to?

A: Yes, most truck toppers are designed to be removable. However, due to their size and weight (especially fiberglass), it typically requires two or more people to safely lift and store the topper. The process involves unclamping it from the bed rails and disconnecting any electrical wiring.
