Not sure where you are located. We have a place in Illinois where we get freeze and thaws, etc. I laid down 4 inches of white rock type gravel on grass growing in a clay soil. The first year there was some subsidence but I learned to put a piece of 2 x 6 a few feet long under each tire and under each leg. I also put some under the tongue jack.
Since, no subsidence and 6 winters later it has worked well and wasn't to expensive.
