Key Considerations for Choosing a Hard Tonneau Cover

Truck Bed Size and Compatibility:

RAM trucks come with bed sizes like 5.7 ft (67.4”) and 6.4 ft (76.3”). Always confirm the cover’s compatibility with your specific model, year, and bed size. For example, the Gator EFX does not fit RAM 1500 models [].

Check for compatibility with RamBox or multi-function tailgates, as some covers (e.g., Mopar soft tri-fold) are incompatible with multi-function tailgates.

Usage Needs:

Frequent Access: Retractable (GatorTrax, RetraxPRO MX) or roll-up (TruXedo Sentry CT) covers are best for easy access.

Heavy Loads: Covers like the BAKFlip MX4 and Gator EFX support significant weight (300–400 lbs.), ideal for hauling gear.

Security: One-piece (UnderCover Elite LX) and retractable covers offer the highest theft protection.

Off-Roading: Aluminum covers like the Lomax or BAKFlip MX4 are better for rugged environments than fiberglass.

Weather Conditions:

Look for covers with EPDM rubber seals and drainage systems for optimal weatherproofing, especially in rainy or snowy climates.

Aluminum covers are preferable in high-heat environments, as fiberglass (FRP) may degrade.

Installation and Maintenance:

Most hard covers, like the Gator EFX and BAKFlip MX4, feature tool-free installation. Watch installation videos on RealTruck’s YouTube channel for guidance, as printed instructions can be unclear.

Regular cleaning with products like 303 Aerospace Protectant can extend the life of the cover’s finish.

Budget:

Prices range from $700 (Lomax) to $2,000 (UnderCover Elite LX). Consider long-term value, as premium covers often come with better warranties and durability.

RamBox and Multi-Function Tailgate:

RamBox-equipped trucks require specific covers, such as the TruXedo Sentry CT or BAKFlip MX4. The Bison Flip Back Tri-Fold is designed specifically for RamBox models with utility rails.

Multi-function tailgates may limit compatibility; confirm with the manufacturer before purchasing.

Installation Tips

Measure Your Bed: Double-check your truck’s bed length and configuration (e.g., RamBox, multi-function tailgate) to ensure a proper fit.

Follow Video Guides: Bison YouTube videos provide clearer instructions than most manuals.

Check Alignment: After installation, open and close the cover to ensure smooth operation and proper latch alignment.

Use Two People for Heavy Covers: One-piece covers like the UnderCover Elite LX can weigh up to 70 lbs., making installation easier with help.

Apply Seals Properly: Remove adhesive tape from seals and place them carefully along bed rails and tailgates to prevent leaks.
