Bug's had a purty tough roof to begin with. You could flip them upside down and spin them around on the roof without much damage to the car. The roof was much of the support for the car. (The car was still little pieces of junk though) It would have needed some extra support for sure but, not as much as you might think. The biggest problem would have been the car was so underpowered it could barley pull itself. There Is no way it could tow anything else.
