The end of the ramp is the part that always gets me.
Many of them have an
increase in angle for the last 6 inches or so. I am sure I am just about to
die at least once when getting it past that transition.
If the cabinet bottoms out at this crest, try putting a piece of thin
plywood or two on the deck of the truck, a few inches in. Even 1/4
inch pieces can help greatly.
