My storage area next to my house not level either. I bought 2- 4X8 sheets of pressure treated 1" plywood at HD and had them ripped in half lengthwise then laid them one on top of other allowing 4 inches stair stepping, one a little behind the next to make a 2ft X 8 ft ramp, 4" thick Then I put my Lynx leveler blocks on top of that for each axle ( 3 high pyramid) so my low side is now 7 " higher and totally level and both axles and tires supported equally. This is good to do if you will be extending your slideout or testing your fridge during off season as neither should be operated if TT is not level. Looks better too level...I hate crooked pictures in my home and crooked TT's!
