We had a 2007 Montana Mountaineer and only had minor items go bad, we traveled from as far as Canada to Texas. Always took 2 long trips a year, so I don't know how many miles we traveled, The RV was a 32Ft 5th wheel and we pulled it with a 2007 Chevy 2500HD SBed We have been RVing since 2000 and have had Truck Campers, Trailers, and now we have an 43ft Toy Hauler...I have a 3500HD now Dual Wheel and what a change from the 2500HD and SWheel...Check the weight of the 5th Wheel before looking for a truck if you will need one, I did tow my Voltage a couple times, and it is about 16K before we put a lot of items into it, now I wouldn't pull it with anything smaller then a 3500, from any of the big 3 trucks....Good Luck on your Choice and good Rving
