For my Bigfoot 25c 9.4 for long term storage, I made a "foot print" pallet with (3) 4x4's cross ways at the Bigfoot recommended locations. In your case, I would just use (3) 4x4's purchased locally. Support the 4x4's by (6) Camco jacks, cheap, lightweight aluminum and they nest. Much lighter than scissor jacks and much more stable (I have tried both). You'll need (10) pieces of 2x stock or heavy plywood to go under all jacks to prevent the jack bases from settling into the pavement or ground. For example (1) 2x10x8 cut into 9 1/2" pieces would work well. Very easy to level and the camper will be rock stable, with little to no load on the 4 camper jacks.
