Newbie - 1st time towing Car on Tow Dolly - Tips?

From experience: Make sure your parking brake is not on and stop after a few miles and double check your tie downs. I also walk around the dolly and toad and lay my hand on every tire and hub to see if any are building excessive heat.

I have found the parking brake partially engaged that way and a wheel bearing on the tow dolly beginning to fail.
