We travel with 16 squares of 15"x15" 3/4 inch treated plywood to put under my jack pads....i use the "jack boards" to level the coach & keep from "punching" thru an asphalt pad or to put down when the ground is soft.
Ive never had an issue raising our coach off its wheels to get the coach level (in fact i STORE it w/ the tires off the ground to prevent flat spotting & premature tire deterioration)....i don't know how people get "level" w/out raising a tire (or couple of tires) off the ground.
when parked on the curb of my in-laws, the crown of the road, is such that i end up lifting my passenger rear and front off the road.
