RamBox, Split Tailgates, and Bed Lengths: How to Buy the Right RAM 1500 Tonneau Cover
Share
You just bought a 2019–2026 RAM 1500. It has a gorgeous interior, an incredibly smooth ride, and a massive bed ready to haul your gear. But leaving that bed wide open to the elements—and to thieves—isn't an option. You need a premium tonneau cover.
You hop online, find a sleek, hard-folding aluminum cover, and hit buy. It arrives, you unbox it, and immediately realize... the mounting rails don't line up. The rear seal is hitting the tailgate wrong. It physically will not bolt onto your truck.
Welcome to the RAM fitment trap.
More than any other modern truck, the 5th Gen RAM 1500 has highly specific bed configurations that drastically alter which covers will fit.
Do you have the incredibly popular RamBox Cargo Management System? Standard covers won't fit.
Did you upgrade to the 60/40 Multi-Function Tailgate? The corner brackets are entirely different.
And did you actually measure your bed to see if you have the 5'7" or 6'4" box?
In this comprehensive guide, we break down exactly how to identify your RAM's unique bed features, explain why you should avoid cheap vinyl snap-covers, and highlight the elite, exact-fit hard covers from BAK Industries, Retrax, and TruXedo that will lock down your cargo securely.

Frequently Asked Questions (RAM Bed Covers)
Are these premium bed covers completely waterproof?
Highly water-resistant, but rarely 100% waterproof.
Premium covers from BAK Industries and Retrax use heavy-duty EPDM rubber seals that route 98% of rain and snow over the side of the truck. Retractable and folding covers also utilize integrated drainage tubes that funnel trapped water out of the bed. While your gear will stay incredibly dry during a torrential downpour, a few drops may occasionally sneak in around the tailgate gaps or the corners during a high-pressure car wash.
Will a cover block my RamBox lockers from opening?
Not if you buy the correct part number.
Standard covers will physically block the RamBox lids from opening. However, covers specifically engineered for the RamBox system (like the BAKFlip MX4 for RamBox) utilize specialized mounting rails that sit perfectly flush inside the bed. This allows you full, unimpeded access to your side storage lockers while keeping the main bed completely secure.
Can I install a bed rack or crossbars with a tonneau cover?
Yes, with a T-Slot compatible cover.
If you plan to mount bike racks, rooftop tents, or overlanding gear above your bed, you need a cover with an integrated Trax Rail System. The RetraxPRO XR is the undisputed king of this, featuring built-in T-slots that accept premium rack accessories from Thule, Yakima, and Rhino-Rack, all without preventing the cover from opening and closing.
