I purchased our camper for a short bed F-350. I added a sway bar, super springs, and stable loads. I tried for 4 months to get a set of Rickson steel 19.5" wheels. We had trips planned and no delivery date for those wheels so I found this F-450 on a local dealers lot with less than 40,000 miles and couldn't be happier.
I now have all the load capacity I need, an 18" extra storage space between the front of the camper and the cab of the truck, much tighter turning radius plus 19.5" wheels. The only downside was it cost a fortune to put on a full set of new tires but I was going to have to do that anyway with the F-350.
