I have driven a lot of motorhomes and most types of semis with trailers but had never used a tow dolly.
I drove my Chevy PU 140 miles to look at a Kia Sportage for sale by Hertz Used Car Sales. The car was in perfect condition so I made a deal on it and needed to get it home. (they were great to deal with and even took a personal check and furnished new tag)
I went across the street to U-Haul, rented a dolly to bring the car home.
The car/dolly towed GREAT, like it wasn't even back there! I ran 65-70 mph most of the way home.
My only problem was when I would look in the inside rear view mirror to see that car tailgating me! :)
