I am almost surprised. You can picture these all you want on flat level ground, but as soon as there is a swail or a lean or a sharp high bump, it changes the whole dynamics of how the vehicles clear one another. I would definitely do some really slow controlled testing before hitting the highway with it.
I would point to Schweetcruiser's Astrodome and its first trip home with the Pathfinder. schweetcruisers.blogspot.com )
Granted, whole different vehicle. But I personally would not let it go to chance that something on a fully restored camper is not going to pinch my SUV-styled high-backed tow vehicle when I least expect it.
