Bare metal jack pads can crack concrete and indent asphalt on a hot day. Some RV parks require pads for leveling jacks.
I also balked at the price of SnapPads. So I went to my local tractor supply and bought small stall mat for $20 on sale ($25 normal price). I cut four 12" diameter circles out of it with a jigsaw, used some 1/2" plywood I had laying around and did the same thing. Cut a circle out of the center of the plywood circles that would clear the jack cylinders and bolts at the top of the travel, added s slot so I could slide the plywood in place. Painted the plywood black, and used four 1/4" stainless carriage bolts per pad with fender washers and nylock nuts on the plywood side (Round carriage bolt heads on the bottom of the rubber pads) and snugged it up. Now I have 4 rubber tennis shoes on my leveling jacks for a whole lot less than SnapPad wanted.
