For the gas RV Fifth Wheel Hauler's out here.
Hi everyone, I've been researching for a used 6 sitter truck. That can tow a fifth wheel GVWR 17K. Boy, it is truly a mind blowing experience! I started with diesel. But, from my research. Diesel...

At 17K you're looking at newer 350/3500 Duallies. The newer crop of Diesels have glow plugs to help with cold weather starting, plus for northern area sales, a block heater is a mandatory option (at least with GMs), which allows you to plug the truck in during extreme cold temps. Also most of the current Diesels will probably get better mileage than your 250 both solo and towing.
At 17k, dually diesel is the minimum. You might even consider jumping up to a 450/550 at that size. The V10 can probably pull it on flat ground but hit an overpass and it will be downshifting.
Glow plugs and engine block heaters are not a new idea. Our last truck was a 92 F250 with the 7.3 and it had both. We had it in Michigan and it always started fine (sold it 2-3yrs ago).
As far as MPG, the old 7.3 got 20-22mpg running around town. Our new V10 gets 14-16mpg running around town. Similar towing 12.8mpg long term vs 9.5mpg.
All engines (gas or diesel) are much happier if you get them up to temperature regularly. So if you have a 2mile commute, both will not like it.
