I only have two trips on mine but have now found the right method to the madness. (with help from FRF and practice at home)
Set were you would like to stay, adjust with blocks under tires to get about 1/4 bubble high on the slide side, level front to rear, set the stabilizers down firmly, extend slides.
That seemed to work perfect on the last trip which was on a gravel pad.
