Nissan Frontier Inflatable Truck Bed Topper Setup Guide

Quick answer

Set up your ARMORDILLO® CoveRex inflatable truck bed camper topper on a Nissan Frontier 6' bed in under 20 minutes by following these seven steps—from positioning the base to securing the air valves.

CoveRex setup steps for Nissan Frontier 6' bed

1. 1. Clear and measure the bed: Remove all cargo, tie-downs, and any tonneau cover. Measure the bed length from the front wall to the tailgate—confirm it's at least 72 inches (6 feet). The CoveRex requires a clean, unobstructed space. Common mistake: leaving a toolbox or spare tire in the bed. They'll prevent the topper from sitting flat.
2. 2. Unfold and position the CoveRex: Lay the deflated CoveRex flat in the bed with the inflation valves facing upward and toward the cab. Center it side-to-side so the edges don't rub against the bed walls. The base should rest flush against the front bed wall. Checkpoint: the tailgate must close fully. If the CoveRex extends past the bed, shift it forward.
3. 3. Connect the inflation pump: Attach the included 12V pump to your truck's auxiliary power outlet or use a hand pump for remote setups. Screw the pump hose onto the main inflation valve (usually marked with a large cap). Do not over-tighten—hand-tight is sufficient. Common mistake: using a compressor with too high pressure. Stick to the recommended 5–8 PSI to avoid overstressing the seams.
4. 4. Inflate to firm but not hard: Turn on the pump and monitor the CoveRex as it fills. Stop when the structure feels firm to the touch and the panels are flat—about 6 PSI. Use a tire-pressure gauge if you want precision. Over-inflation can damage the drop-stitch core. Checkpoint: press on the center panel. If it depresses more than 1/4 inch, add a little more air.
5. 5. Secure the tailgate seal: Lower the tailgate and close it gently against the CoveRex's rear panel. The CoveRex includes a soft seal that compresses against the tailgate to keep out dust and drafts. If your Frontier has a tailgate step, make sure it's stowed. Common mistake: forcing the tailgate shut. If it won't latch, the CoveRex is too far back—deflate slightly and reposition.
6. 6. Check all air valves: Tighten the valve caps by hand. The CoveRex has multiple valves for inflation and deflation. Confirm each one is sealed to prevent slow leaks during the night. A small hiss means the cap isn't fully closed. Checkpoint: run your hand around the base. If you feel a draft, the tailgate seal needs adjustment.
7. 7. Test stability before loading gear: Climb into the bed and sit or lie down on the CoveRex. It should feel solid with minimal give. If it wobbles, add a few more pump strokes. Once stable, you can load your sleeping bag, pad, and gear on top. Common mistake: loading heavy gear before checking stability. The CoveRex needs to be fully inflated to support weight evenly.
