I have a Bumper pull Arctic Fox. It has carpet around the couch and dinette, none on the ceiling. It's a 2004 and we drag it around 13,000 miles every year. I am going from Va-Gulfport Ms-Ft Worth-OKC-Covington OK-Va in April-May. Still have never had a problem with it. Yes I know about the Tornadoes having live in Ok 15 years. That will be a RT of 3300 or so.
