Thanks for the tip about the horse stall mat! My 2014 LTV Free Spirit is parked on 5/8 Minus crushed rock gravel. I got new tires last year before storing on the gravel pad and noticed when I drove van off the pad after sitting for a while the tires had a bunch of gravel imbedded in the contact patches of the tires. Since I have to drive across my lawn from the pad to get to my driveway, this gravel was being deposited on the lawn! Just driving onto the gravel pad did not pick up the rocks but parking on it for a period certainly did. I learned to drive forward on the pad about 1/2 wheel turn, get out and knock off the gravel with a gloved hand, and then drive off the pad and onto the lawn.
Solved the problem today following your suggestion. I bought a 4' x 6' x 3/4" horse stall pad from a farm store, along with some 3/8" x 5" galvanized carriage bolts. I raked back the gravel from where the tires normally are on the pad and installed 2' x 2' squares of the horse stall pad at the front tire areas and 3 x 2 rectangles in the rear dually areas. I drilled holes in each corner of the horse stall pads and hammered the carriage bolts through the pads and into the ground to keep the pad from moving when coming and going. I then raked the gravel back up to the edges of horse stall pad sections. Works perfectly! Cost $44 for the stall pad.
Side note: Living in the Northwest, we get a lot of rain in the winter. I noticed that the humidity in the van was getting up to 80%. A friend suggested that part of the problem may be due to ground water evaporation coming up through perforations in the floor of the van. I raked all of the gravel back from under the van, installed clear plastic sheeting, and then covered the plastic with the gravel again. The humidity in the van did drop significantly.
So lessons learned when storing the van on gravel: Plastic under the van to reduce humidity and horse stall pad or something similar under each tire.
