I tend to agree with craig7h.
I was in the automobile business for 30 years, so always had numerous options of what I wanted to take with us on a trip. So, I found that a Demco all-galvanized dolly with surge brakes fit our needs the best (plus I used it in my business extensively).
Although it limited us to a FWD vehicle, sometimes it was a small van, sometimes a very economical puddle-jumper, and sometimes our own personal Audi A4 convertible. We never had any issues with what to do with the dolly when we reached our destination, and with a drop-down front wheel added, although the dolly was heavy, it was still very maneuverabile.
