Camper shifting in pickup box.

I've got the same Lance Camper Guides as Jefe 4X4 posted.

But we use a thicker, horse stall mat under the camper. As they come in 4ft by 6ft sizes, I had to purchase two, and cut one to fill out the 8ft box. 3/4 inch thick. About $40/each at stores such as Tractor Supply and other farm/ranch type supply stores

Camper hardly moves.

I drop a 6x6x12" wood blocks in the front corners of the bed.

We use this rubber mat with Torklift tie downs and Fastguns. I haven't noticed much if any shifting of the camper.

Always travel with full fresh, empty black, grey. Also, try a spring loaded tiedown. Don't overtighten with your current setup.

When backing in I get it as central as I can, then lower it until it is between the wheel wells but still about 4 inches off the bed. I then slide in two 1"x6" about 6 feet long, then lower the rest of the way. It works pretty well.

Do you use a thin rubber mat in the bed? It sounds like the symptom I had before I used the mat and ditched the real problem: the corrugated plastic bed liner. The next step was to hold the bottom of the camper in a rack. The quick and dirty solution is to use 2x4's as spacers between the fender wells and the TC. One step up is to use metal stops fore and aft. I use the Lance Camper Guides, but there are many better solutions if you go back and search camper guides.






One other oft missed woe with the camper sliding around is it puts undue stress on the tie downs (one side or the other) and can lead to premature TC frame/attachment area failure, whether wood or aluminum.

Had the same problem even with the cow mat, as above you just need to wedge between the camper tub walls on each side and the wheel wheels of the truck box.

I painted 2 pieces of 1x6x 4 feet deck planking, painted white and place them on their edge, then just back the camper in between them, they even help as a loading guide, once in there the camper cannot move.

My camper used to walk around the truck bed. Even with the rubber horse stall matting in place. In the end I screwed timber rails to the lower sides of the truck camper so it matched the width between the wheel arches, pinning it in place. Obviously you wouldn't want to do that with a nice new camper, but there have been other threads on this forum covering this and people have created various solutions in the truck bed for holding the camper still (I think there was a thread about 3 years ago). You might find a link to it in the Truck Camper University sticky thread.

I have had that issue for years, in several different trucks/TCs. I usually just ignore it. I have stopped it on a couple of TCs by having a rubber horse stall mat between the TC and truck bed. I have also put a 2x4 on edge between the wheel well and TC. I have had the problem more on rough road with a high crown.
