I was going to help my son drive his car back to college. About 700 miles one way. I'm thinking of using his tahoe to pull my car and then leave him there and drive my car back. Other than unhooking the drive shaft would there be any other concerns or dangers. If I took my front bumper off, could I have a tow bar built to hook to the bumper extensions? Any ideas? I could rent a dolly from uhaul but it probably won't be cheep. If I did that I'd probably just pull the front wheel drive pontiac.
