Talking PUPs here. Usually roof has to raised a tad to even open door. Stuff is often stored on floor for travel.
I found gluing a level cross-wise calibrated in inches works really well for getting the correct number of orange Legos under the low wheel. First time, every time, and box of Legos is light, compact, and less than $35 at Wal-Mart. That way I can level before raising the roof (recommended order of events).
And gets it level enough I can't detect any error while in the A-frame.
