As stated difference of opinion. I bought the dolly for $700 20+ years ago. Bought tires for it twice (I carry a spare tire but have never used it) We travel extensively and I only remember one time having to unhook the dolly. At home I store it in the alarmed garage, 52X40 garage, along with the DP. Not much trouble with thieves out here in the country. I am 82 years old and can move that dolly around with 1 hand, drop it on the ball, plug in the lights, and its ready to go. So since I never unhook it, except at home, all I have to do is unhook 1 pin roll the car (any front wheel drive car I have at the moment) on the dolly, tighten down 2 straps, put the pin back in and down the road I go. Me and that Road Master just don't get along I guess and I was using tow bars 60 years ago when you, some times, just clamped them on your front bumper. Remember those? Anyway that tow bar that came with this car is out there in the back of my pick up hoping to find a loving new home..Anyway, just having some fun here. Everyone be safe and have fun on your travels
