An auto car on a tow dolly?

I know you're trying to be safe, but I'm telling, you the U haul dollies are fine. We brought my 70 dart home with one, using an 04 Xterra, pulled like a champ. It was over 350 miles.

We also brought home a 76 duster with one. I wouldn't worry about tongue weight, trailer brakes etc. Just take your time, no need to go over 60, and be done with it.
