Decided to go the more cost effective way and make my own body cart out of wood for about $150. A few 4x4’s, some Harbor Freight 6” Casters, and some miscellaneous hardware. This is a temporary solution to get my 1969 Camaro shell from the body shop, onto a trailer, and back to my place after it’s done being painted. These dimensions allow it to go up a ramp on a U-Hail trailer. It will sit just right outside the pinch welds under the car.
