Pads for under Leveling Jacks?

We have stayed at a couple of campgrounds where pads were required because of soft surfaces or blacktop. If the pad is concrete there is no need. Don't buy plastic pads for a MH with auto levelers. Unless the ground is firm and level they will shatter. My pads are 1' square made from two pieces of 1" thick fir plywood with the grain running in opposite directions. They are glued and screwed together. I drilled a hole in one corner so I could use rod with a hook in it for positioning under the pad foot. A friend made ones similar to mine with an additional layer of stall mat on each side and a drawer handle affixed to on side. That works great for his fiver with auto levelers, but they would be to heavy to wrestle around under my MH. He reasoned that the stall mat helps the pad self adjust for uneven surfaces.
