Thanks for the input. I am trying to make sense of the regulations at my state's motor vehicle site as to what is commercial since that could be an big factor. A 3/4 ton would work for just the truck camper but we will need to pull a 2000# trailer at times with the camper installed. Right now we are looking for new gasser. Diesel is great, I have a Sprinter. Mileage and power is just fine, but as I travel to different fishing locations it starts to become an issue. Granted the Sprinter may be the least forgiving of bad or biodiesel, the new Detroit trucks probably will also have issues. As for brand, it is too hard to narrow down at this point. It would be used for long highway travel from out east to the west fishing areas and then on those access roads. We always had GM growing up and have an old 3500 on the farm that keeps running despite the massive rust. Still the PR related to Fords make them look to be the choice of flatbed campers.
Assuming that I don't add another tractor/vehicle rebuild to the list, which I can't, it would mean a new one. Looking at the truck sites I notice that there is not an option listed for a chassis without a bed except for the commercial. Is there a way to order one without the bed and also save money?
