So presuming you’re on level enough sites that the step height doesn’t change alot. But even if it does, those premade plastic stabilizer jack risers, the premade Lego blocks, bigger piece of lumber like a 6x6 8x8 or 12x12 and a couple of the 2xs or some plywood for adjustability, foam block with a piece of wood on top, couple log rounds, couple 4x4s or 4x6s as cribbing, paint cans, a cheap screw jack for spare tire on your car, a car rim and a couple boards, a RV leveler or 2 (kinda same as the screw jack)….off the top of my head.
Let me know if you need more suggestions for this conundrum….
