Had a tow dolly for a car that could not be towed four down. Prefer not to have a tow dolly. That being said, if you go to a place to stay for a week or more, than the extra work it takes to unhitch a tow dolly and store it somewhere else in a park it isn't much of a problem. If you are lucky to have a pull through, no problem. You do have to pay a lot extra on toll roads and bridges for the extra axle. I was surprised how much an extra axle adds to the toll cost.
