I sold my 2004 F350 and picked up this 21 F450 in January plenty of truck to pull the passes around Colorado. My brother works for Ford so I get a really nice discount. November we traded our 2006 sunny brook bh for a 22 41v15 another really nice up grade I won't have to load the RZR on the truck any more. I went with Gen Y goose box to save room in the truck it's much easier to pull that ball out than a heavy hitch. I have an on board air system I built Puma 1\3hp pump 150psi an old scuba tank for reserve, quick disconnect at the back of the box and air bags. Pump and solenoids that run everything I tucked in behind the back seat. My wife retired this past summer and I have about a year to go then we will be on the road a lot more.
