I has some extra 3/4 ply laying around and my track saw setup from working on a customer built in. Figured 12x12 at 3Ē thick would be good for stabilizer pads.
Gave them a good coat of exterior poly to keep them in better shape.
Might add some 3/4 conveyor belt to them also to keep them from slipping.
I had a customer give me this wheel chock a few years back for my work trailer but it never fit my work trailers. Is it worth using or are they junk?
