BAD idea IMO. So, you have about 6 inches of clearance it looks like? So what happens when you are on an up or downslope and you hear a horrible scraping noise comming from yuor roof? Plus, I don't know if I trust all that weight being pulled by the 4 roof members.
Thats a funny video, similar to that VW one that I saw earlier today. Definitely a later model Suby than 58 though... I wonder why they never put these campers, or the towing methods into production? Safety reasons I'd assume?
