I read your post, and the first thing that jumped out at me is to be sure to check the angle of your tow bar. Having driven a Mini for several years, it is very low to the ground. Not familiar with your coach, but I would imagine the hitch is quite high. I've read up on several tow bars, and as I recall, they specify that the tow bar should be very close to level when hooked up. Just a thought to check the website for your particular tow bar - you may need to use some form of drop hitch to maintain tow stability (such as BX88241 7” Rise/Drop Receiver, 10,000 lbs, 12” long | Blue Ox
Every body has their preference for dolly/flat/trailer towing. I'm firmly in the flat-towing camp for many reasons. First, my coach is 44' long, and I tow a Yukon XL behind. Several times I have found the need to disconnect to maneuver (Sad to say, usually because I made a wrong turn
). With flat towing, I can disconnect, maneuver an re-connect in 10-15 minutes.
I also have to rent a garage to store my coach. The deepest garage I've ever been able to find is 50' deep. Not much room left for a dolly or trailer - and I don't want to rent additional storage space.
Regarding tow damage: RV's kick up debris from the wheels. I believe the higher ground clearance you tow vehicle has, the less of a problem debris will be. My toad sits comparatively high, but I've bought a Blue Ox Kar Gard screen (BX88255 KarGard II | Blue Ox
) to go between the coach and toad. Not sure if it will be a problem, but the toad is new and I really don't want to chip it up!
Best of luck to you!
