Parking on area with dirt/grass stability

Nanidh12, We almost never camp in an RV campground, and we camp in all 4 seasons.... from dry summer, wet fall/ spring, to snow and below zero temps. I used 2 pieces of 3/4” plywood, glued and screwed together (laminated). I cut ours to a 16”x16” footprint, you could likely go smaller, as our unit weighs 20K pounds. I also put a small piece of nylon strap between the lamination on one side to serve as a “carry handle”! If we will be camping when temperatures may drop to well below freezing, I have some “tar paper/building felt” pieces pre-cut to go beneath my plywood pieces. This will allow me to take my plywood pieces home with me......not frozen to the ground! We’ve never had to leave any tar paper behind ( it seems to “not” stick to the ice), and hopefully never will! memtb
