Thanks for the replies. I'm getting some good info here. I did starting think about insurance for the box truck, and if I had to register it as a commercial vehicle, and if I needed a commercial license for it. Just more research for me todo. I also did take a quick look at Budget and Penske. I also was thinking of UPS, though most of there trucks are probably too tall. And yes, I was thinking about putting the car IN the truck.

I should have pointed out that I don't plan on getting an enclosed trailer, and may just go Dave's route and get a tow dolly. So I'm leaning towards the Van option.

Any other comments? Should I also be looking at extra cooling for the transmission, or some other addon that will keep the engine from failing during a tow?
