Full extension of landing gear making me nervous

I agree with the OP, I have a number of pressure treated 2 X 10's of varying length that I put under the pads. I try to compensate for uneven ground as best I can, before pushing the "auto level" button! But you do what you have to do, the fridge does not like being un level, and I hate rolling out of bed! So if it takes a full extension to level the rig, so be it!
