I made my own 6 years ago from an eight foot treated 2 x 10. Eight pieces about 9" x 12", the size that two wide would just fit in my smallest 24" wide storage compartment. After a few years a couple of them split, so I just stacked 2 of them cross wise and screwed them together, installed a small eye hook to pull them out and now they work fine and give me 3" of lift under each pad and are strong enough to resist bending on soft ground the way a soft plastic or rubber pad would.
