Our Arctic Fox is 33 ft. total. The only campsites we have found to be a problem are state and county. This is partially because the large slide comes out about 43 inches and creates problems with trees, shrubbery, etc. on the 5'vr sides. I carry a measuring tape for that purpose. My D.W. and I have never felt interior space was a problem even with visitors inside. We have traveled from So. Calif. to Florida--to northern B.C.--to Alaska, and points in between. Also, at this length I can keep the 5'vr in my driveway for storage. Lars
