Easy to do, if you're very strong (as in superman).

Open tailgate. Stand below tailgate, facing van. Grip right pillar with
right hand, left pillar with left hand. Lift and rotate (either way will
do). You may need to lower van onto its side at the 90-degree point to
change your grip. Continue rotating until inverted. Lower gently. voila.
Van turned over from behind.
