I'm glad to see that I am still able to be amazed at stupidity.:lol:
Shoot, just cut that hitch back up to the trailer, put the 5th wheel on the roof, and it might work! Ok, with lots of internal bracing and whatnot, but it has to be better than that!
They actually sold a rig like that back in the 70's. A 5th wheel trailer with a gutter mount hitch. It only worked on large 4 door sedans, but it was an interesting idea!
