Top Tips for Picking the Perfect Truck Cap
Aug 4 2025
Choosing the right truck cap depends on your truck's bed size, your intended use (cargo, security, or camping), preferred materials, and desired features like windows, locks, and insulation.
Know Your Truck Bed Size and Fit
- Truck caps come in many shapes and sizes tailored for specific truck beds. It's essential to measure your truck bed's length and width accurately and then select a cap that fits perfectly to avoid leaks, damage, or fit issues. Manufacturer specifications will specify compatibility with various truck models and bed designs, so always verify the cap fits your exact truck make and bed length.
Choose the Right Material
- Fiberglass: The best choice for versatility and durability, especially if you want to use your truck for camping. Fiberglass caps are molded for a perfect fit, offer insulating properties, and can handle heavy rooftop loads. They also come in many color and height options.
- Aluminum: Lighter and often less expensive than fiberglass caps. Suitable if you want to save weight, but generally less durable, prone to dents, and noisier in rain. Aluminum caps tend to have fewer style and color options and are less favored for recreational purposes.
- Commercial Caps: Made of thick aluminum without windows, focused on rugged utility use like storing tools. They are durable and often outfitted with shelves or lockboxes, but limit interior space for activities like camping.
Select the Style and Height
- Regular or Cab-High Caps: Match the height of your truck's cab. They offer a sleek, aerodynamic look and keep your vehicle's clearance unchanged. Suitable for normal cargo protection and modest storage. Limited headroom if you want to sleep or spend time inside.
- Mid/High-Rise Caps: Extend above the truck cab's roofline. Give more cargo space, improved headroom, and greater comfort if you plan to camp or spend time inside your truck bed. Slightly less aerodynamic but minimal impact on fuel economy.
Consider Key Features Based on Your Needs
- Windows & Ventilation: Sliding side windows are crucial for airflow, especially for camping. Bug screens on windows keep insects out while letting fresh air in. Rear windows add natural light; blackout curtains can manage privacy and light during sleep.
- Locks: Security is vital if you carry expensive gear. LEER truck caps come with locks or locking options to deter theft.
- Insulation & Headliner: LEER fiberglass caps offer upgrades like carpeted headliners to improve insulation, reducing condensation and improving comfort for camping in cold weather.
- Roof Rack Compatibility: If you plan to carry kayaks, bikes, or extra cargo, look for caps with roof rails or mounting points.Lighting: Interior LED lights can make the cap interior more usable and enjoyable.
Additional Tips
- For heavy gear or rooftop loads, check the cap's load rating. Choose a style that suits your truck's appearance if aesthetics matter to you. By carefully considering your truck's size, intended uses, material preferences, and desired features, you can select the perfect truck cap that enhances your truck's utility, protects your cargo, and suits activities like camping or overlanding.
