I see two differences between your unit and mine. My "upstairs" doesn't protrude as far as yours does. You definitely want to measure the height of your unit and put that over the windshield. You won't be able to see low hanging lines or other overhead hazards. A low awning for instance will make a huge racket if you top out. Mine is around 9'2 in height but I've got 9-6 over the windshield so if mechanic or new owner drives it, they will make sure to have plenty of room. If they forget and go under something 9'5, there's a little extra room.
The second difference is pretty critical. My van doesn't reach much behind the rear axle. You have an extra 12-18 inches over mine, plus the carrier. Be aware when you tunr sharp, either way, that overhand will swing out. It will be easy to clip a post or parked car. You have a clean straight unit and I'd hate to see a crumpled corner like I see on a lot of motorhome and trailers. The motorhomes with the rear axle around the middle of the body get it most of the time.
