I was wondering I am looking at going back to a MH and Winnebago brags about there safety cage, doesn't all of them have to be built to a NHTSA safety standard? and if not why?
I doubt there is a great deal of difference between Fiberglas coach builders in a rollover issue. These coaches are welded and bolted onto frames with outriggers. They do not do well off their wheels. In my opinion you're better off paying attention to build reputation than coach framing.
As for this statement;
"They are also the most expensive to repair, and for that reason go to the junk yard when damaged."
