Yeah I would be worried to forget and then to make a 90 degree turn and do damage and yes never back up, unlatch and move it then relatch. I have a cousin with motorhome and suv in tow that says to me I just have to plan where I go as it gets pretty long.
I long for an Aerovault, with a Crew cab truck, but then I would need a house in the warm states, and we still can't drive there
if length and storage is an issue I would think one could build it with a removable section one pipe fitting into the other held with D ring pins or bolts to fit it in your trunk, that would be better and easier to handle.
