Can't be done. Not cheaply anyway.
Not renting the U-haul, which is 4 inches shy of the ceiling of the parking garage (not enough clearance to make me comfortable) and any trailers I can rent are even more expensive. If the truck were closer to 7 feet high and not 7' 8" I'd feel more comfortable, but that's just not enough to risk spending even more to cover damage to the truck.

So unless someone coming to the show has a big-a$$ trailer or truck with them, the photo will have to suffice.

Thanks for all of the offers for help.
