With our first Class A we used an open aluminum trailer. With our Newmar DP we used an enclosed trailer. We later switched to a tandem tow dolly so we could still haul the motorcycle and car together, but it was a constant worry because I gave up my ability to back up any distance.@FL-JOE , I have never towed with a dolly. I've flat towed for 15 years, and a few times I have had to disconnect to get out of a predicament.
To me, flat tow is superior, but you do bring up valid costs of this arrangement. Once you factor in the tow bar, brake system, lighting, and possibly new vehicle, the dolly is very much a strong contender.
Can you share some knowledge on the different dollys and or flat bed requirements?
I believe you flatbed, Since you mentioned backing up. That would certainly be compatible with all vehicles.
Any additional information you share can help others as they are planning this lifestyle. Not everyone wants to buy a new car just to get an rv.
