I have a couple of 14x14 squares of 3/4 CDX with a 2x8 along one middle axis. PT would have been preferable, but these were just some scraps laying around. The 2x keeps the point load of the jacks from post-holing through the ply.
Bearing capacity of soil surfaces are relatively good... just need to spread the load.

And if you can't get the camper high enough to get the rear wheels over a board cross ways under the front jacks, just unload it on some small pads, pull forward, set the front of the camper down on the back of the truck bed so you can put some bigger pads under the jacks.
If it's going to be there a while, don't just leave it on the jacks. You can, but can press the load a lot better on to a couple saw horses under the belly. You can build a couple sturdy saw horses the right height pretty cheap. Put some pads under those legs too.
