Camping off the truck

I routinely use wood blocks even when storing my camper on an asphalt driveway. Also check to be sure your camper is rated for use off the truck bed. Even if it is I would consider some additional support. A few stacked pallets work well. This will support the floor, reduce sway and take some of the weight off the jacks.

I have a couple 4x6 pressure treated blocks I cut 12" long. But in 20 years of truck camping, I've never used them under the jacks, just use them to drive the truck tires onto to level the camper if I leave it on the truck. Don't think I've ever put anything under the jacks?

Oh, I guess I did, because the jack was too short to reach the ground.

I'll go with the over thinking thought. Doesn't take much, and good gravel should be enough regardless. But use a small chunk of wood, like a 2x6, if your slightly concerned. Just going from a stock 5" diameter leg pad to a 10" piece of 2x6 cuts 1500 lb load from about 115psi to 27psi.

Now I am thinking about using 1/4 x 12 x 12" steel plate. That should spread the load enough. My camper has a basement and we often have it sitting in our shop and use it. Pretty sure its not going to have issues with sagging floors.

Plywood will not split. Stacked up couple inches high, much stronger than 2X. Larger footprint. If lot of rain, or long time, think the glue might let go? Cut a plastic tote to cover them.

Oh Jesus….here we go again.
You’re an experienced camper. This is about as basic as it gets.
None of us know the bearing capacity of the soil you’re setting it on.
But even ifn it does settle a bit, you have these nifty things on each corner that work with the push of a button called leveling jacks….

Or go visit the thread started by the guy in Cananada a couple weeks ago. There’s like 6 pages of nothing but supporting the jacks of a truck camper 101 there.

Or I'll save the need for any other replies or speculation. Cut 4 2xsomething boards or 12"x12" pieces of plywood 1/2" or greater. Basically anything that's about 1sq ft of area. Use that. If that's not enough, you will likely get your shoes sucked off your feet from the mud before you actually make it to the camper steps.

It is.

Well I happen to have part of a sheet of 3/4" plywood. I can cut 8 12x12 pieces and use two under each foot. Thanks for all the help. Never having set it on anything but concrete and seeing all the rain they have been getting I just wanted to be sure it was not going to sink.

I can for a fact say don't use the yellow jack pads, the jacks slide on the plastic. Never had an issue with 2x12's cut at 1ft length under each jack.

Good advice.
Any sort of stout scrap lumber will suffice.
Dimensional lumber usually becomes kindling wood after a while when it splits. But I use what’s on hand.
