I have a 2015 Rockwood HW276. I parked and set it up to unload from last trip and getting ready for this weekend. PUP is still set up but I want to turn the fridge on and load it in the morning. The PUP is level front to back but it is not level side to side. I have a BAL leveler or an Anderson but cant use either without putting the PUP down and moving it to cement. question is can i turn the fridge on and run it even if its not level front to back? fridge is located along the side on the PUP.
