I measured the distance from the bottom of the jack to the ground, and it is 22", when the camper is loaded onto the truck. So the height of whatever method I use--square boards, concrete blocks,etc. will be less than 2' high. I don't see any danger of squares of wood 12" square toppling over when piled less than 2' high, even with 700 lbs of pressure on each one. I have some pressed plywood shelving material I found, and I am going to cut them into square foot pieces and glue them together. They'll never get wet, they are inside.
That last sentence has been proven wrong many times but it is your choice so good luck
