I haven't been pleased with the inexpensive ones I've had either. Recently cut up some 2'X10" pressure treat in 6' lengths (at 12' used them to slide the new A/C unit to the roof from truck tailgate early this year . . and slide the old one down, much as I wanted to just chunk it over the side, ha!). I have one board under the curb tandem and three under the street pair to level at this park (and keep tires off of gravel better described as rocks). Since the back of the truck is a "garage" this was an easy decision. Haven't decided yet about stabilizer pads . . the lego's are okay for that for now.
