Jacks work much better if you don't extend them very far. Get a couple of sets of LYNX Levelers.. those big lego looking things. if the corners are far off the ground put five or six Lynx blocks there and then extend the stablizers.
Lynx levelers also work well to build up a "ramp" for side to side leveling. Bottom row five blocks, next row three blocks next row two blocks, and one on top if you still need to go higher. Overlap each row like lego blocks and they all lock in. Put them in front of the pod wheel and drive forward. Also get some chocks.
Speaking of chocks, anyone stay at Cumberland Gap State Park.. ? Yikes... !!
