In 2002 we bought our 1st Camper-5th wheel-an Arctic Fox 28 5D-Bunk model-not made anymore. Didn't have problems to speak of-kids grew up-bought a larger Arctic Fox 5th wheel-29 5T. Pulled both with an F250-6.0 Diesel,FX4,4x4,Super Duty, Crew Cab. The 2nd A.F. had about 50,000 miles on it. From So. Ca. had been to Yukon Terr.-all over B.C.- coast to coast U.S.A., and all over western U.S. A.F. is made by Northwood Mfg., in La Grande, OR. They are well made-Northwood makes the Trailer and the Camper-they are a 4 seasons RV-built for going off/on road-has shock absorbers. https://northwoodmfg.com/. Am now older-have a Class C.
