Get yourself a treated 4X4 or two, a 2X8 or 2x10 and a length of 1/2" rebar.
Cut the 2X8(10) to create a square, cut the 4X4 to what ever length you need, cut the rebar 12" longer that the stack you need. Stack the 4X4s with on piece of the 2X on top, drill a 9/16" hole trough the 2X into the 4X, now put another pair of 4Xs under the first pair drill and repeat.
When you disassemble your new jack pads make the corners 1, 2, 3, 4 for the first set, 1A, 2A, 3A, 4A, and repeat with the remaining material.
When you get to the campground, you have a nice set of building blocks to play with, while everyone else is trying to do a balancing act.
