Maybe I'm reading this wrong. Is there anyone out there seriously considering putting utility bed and a camper on a half ton? That would be insanity. We have a 1 ton with an FWC in a utility bed. Except for the gas mileage the thing is flawless. A minimum for utility bed in a camper installation would be at 3/4 ton, and while you're at it, if you have the option, just go to a 1 ton. How on Earth could you camp for any length of time in a half ton with a camper and not be overloaded? If you're making day runs? 1/2 ton will be great. Why bother with a camper & utility bed at that point? That doesn't make any sense. Driving down the freeway at 70 miles an hour in an overloaded vehicle? Not for me, no way, not anymore. Not at my age.
As I said, I'm getting horrible gas mileage. I have the 460 gas motor. Go with the diesel if you can, the mileage is going to be way better.
