Does the tow vehicle also need to double as a daily? If not, how about a box truck and an open trailer? One car and stuff in box, second car on trailer. Unload the car on the trailer, ramps from the box to the trailer to get the car out of the box. If the trailer is under 10k GVWR, you can tow it with a 26k GVWR tow vehicle and a standard license.
