When I picked up my 397 the tech at the dealer said to make sure you are within a half a bubble on a level side to side. I know about the errors you can get if you extend the levelers to far. He said to carry a 2x12x8 and 2x8x6 for 3 inches lift. If that doesnt cut it move sites.

I thought I have carry around that much wood? I assume the plastic squares are not strong enough for the weight. What does everybody use for preliminary side to side before auto leveling?
