My reason for using a dolly was because it offered me the opportunity to tow our Toyota Camry as well as any other front wheel drive car or SUV. Also at the time I bought our first dolly it was about $800 new and I couldn't get a car set up 4 four down that cheap....Bird man in all these years only once have I been put in a position to have to back up. 10 min to unhook car and dolly and another 10 to hook it back up. About 10 years to get over being stupid enough to get in that position. I also have a Featherlite open trailer if I need it.
