I just took measurements on my enclosed car trailer and the Series III isn't going to fit without going through alot of hassle removing the roof and repositioning the windshield. Under normal conditions I wouldn't think twice but not sure really how rusty the windshield mounts are and don't want to open up "a can of worms" if not needed. Anyone ever use a car trailer from UHAUL? Was thinking the tandem trailer not the dolly. Will be transporting it approx. 1000 miles so I need something safe.
