I've used that size U-Haul truck before, and it's best to pad and ratchet-strap the games to the tiedown bars on the sides of the box. I had no trouble moving 9 or 10 games. Remember there is a "hump" on each side where the wheels are. Beware the aluminum loading ramp is only a bit bigger than the wheels of most utility hand trucks so be very careful loading and unloading on that ramp.
