Raising truck camper height

Plywood, use a couple of 3/4" sheets glued together as a spacer. Alot more forgiving to abuse than foam and won't blow out of the truck bed if you forget to remove it after unloading the camper and driving around ;)

Home Depot sells pink and Lowe’s sells blue; I did not know this when I bought mine so I’m stuck with pink.

My last camper was a AF 1140 (now travel 5th wheel) --- things don't get much heavier --- my solution to adding a little height : sandwich 1 inch closed cell foam 4X8 sheet between sheet of 3/4 marine plywood and pickup bed (bolted through to be fixed) --- killed two birds with one stone, added height without worrying about crushing/tearing foam and added insulation which kept floor warm to bare feet --- PS: if me and DW were not 72 and needing more creature features ( such as couch and bigger shower space) I would still have my AF

A 4x8 sheet of foam or plywood is 4,608 square inches. Roughly 1 pound per square inch for a camper that weighs 4,600 pounds. If one end is heavier than another, I would imagine the foam would 'self level' as it compresses under the additional load. If excessive compression happens, add additional foam UNDER this now-customized. mold of foam that matches your truck.

I imagine that the ribs in the bed of the truck are roughly 50/50 raised to recess, making the load per square inch on the loaded foam underneath double what the load is distributed on the top.

My truck's bed is deeper toward the tail gate than it is at the cab end. Makes my camper looks squatty in the back and the clearance between the camper sides and bed rail not parallel. I ended up making a wedge to level out the camper to the bed rails for a cleaner look. It also keeps fewer bugs from smashing into the camper behind the truck's cab and I imagine the air resistance as well is reduced somewhat.

I have an aluminum frame 10' camper. I have the standard rubber mat, and screwed 3, 5/4 plastic porch decking lengthwise, front to back. Works great.

I use the pink foam board on an 11.5 camper and have never had issues with it “rocking” on the rear edge. It works great, costs little, weighs almost nothing and even adds insulation. What’s not to like?

I have had to use foam on every truck and camper combo I've ever owned.Older TC and a newer truck seems to be the issue....

Vinyl isn't slippery when overlain by foam board.

vinyl is slippery.

I use a layer of vinyl fence boards (tongue and groove) then a 2" thick foam board (pink) from HD over that. Works for me and my lightweight TC.
