The Knee-Crusher Trap: Why Spray-In Liners Are Ruining Your Cargo
Share
You just bought an incredible 2019–2026 Ram 3500. You want to protect the massive steel cargo box from rust and scratches, so you pay the dealership to coat it in a thick, heavy-duty spray-in bedliner. It looks incredibly rugged. A week later, you load up a highly expensive, premium cooler and your heavy-duty tools, and hit the highway.
When you arrive at the campsite, you crawl into the back of the truck to grab your gear. Instantly, you are in agonizing pain. The abrasive, sandpaper-like texture of the spray-in liner literally shreds your bare knees. Worse, as you look at your expensive cooler, you realize the relentless highway vibrations ground the plastic bottom of the cooler into the abrasive liner, permanently scuffing and destroying it.
You just fell directly into the Knee-Crusher Trap.
Spray-in liners are great for preventing rust on the steel, but they are absolutely terrible for the cargo (and the human) interacting with them. You don't need to put up with sliding gear and bleeding knees; you just need impact-absorbing polypropylene.
In this guide, we explain exactly how elite cargo engineers at BedRug utilize 100% waterproof, carpet-like plastic fibers to create an indestructible, knee-friendly armor for your bed. We'll show you why loose toolboxes are a highway hazard, how the UnderCover SwingCase locks your gear down, and how to safely command your payload.

Frequently Asked Questions (Bed Accessories)
Will a BedRug mold or smell if it rains on my open Ram 3500 bed?
No, it is 100% waterproof plastic.
This is the biggest misconception about BedRug. It looks and feels like carpet, but it is constructed entirely from closed-cell polypropylene foam and plastic fibers. It physically cannot absorb water. If your Ram 3500 bed fills with rain, snow, or spilled battery acid, the liquid simply drains through the factory weep holes. It will never mold, mildew, or rot.
Can I install an UnderCover SwingCase if I have a 5th-wheel hitch?
Yes, it clears massive in-bed hitches perfectly.
Because the SwingCase mounts tightly against the inner bedside walls and behind the wheel wells, it stays completely out of the way of the massive steel rails and pin boxes of 5th-wheel and gooseneck hitches. It is the absolute perfect heavy-duty towing companion to store your hitch pins, grease, and heavy-duty tow straps.
Do I have to drill into my Ram's bed to install the AMP Research BedXTender?
Yes, minor drilling into the D-pillars is required.
To ensure the massive aluminum cage can securely hold the weight of shifting cargo or an ATV tire, the pivot brackets for the AMP BedXTender must be permanently bolted into the heavy-gauge steel of the truck's rear D-pillars (the vertical metal columns right inside the tailgate opening). It is a simple, highly secure installation.
Armor the knees. Anchor the gear.
Stop destroying your expensive cargo and shredding your knees on abrasive spray-in liners, and absolutely refuse to let loose plastic tubs violently smash into your tailgate. Upgrade to a 100% waterproof, impact-absorbing BedRug liner and a bolted, lockable UnderCover SwingCase to build the ultimate, highly organized tactical cargo box.
