If you're considering the possibility of a fifth wheel, I'd suggest stepping up to a F350/3500 series truck. The 10K GVW on all the 3/4 ton trucks seems to be a "brick wall" that's self imposed by the manufacturers, but one that makes owners face the "legal limits" instead of the "physical limits" of the truck.

If you're positive that you'll only have a travel trailer, then most any properly equipped F250/2500 series truck should do what you want.

As for the 2017 Ford truck, be aware that the gas engine (6.2l) now uses a "lighter duty" version transmission. Ford says it's 'robust with improvements in shift points to enhance the engine's performance". But, they just recalled all of them because of a "parking pall problem".... The transmission in the diesel trucks remains "tried and true" with 7 years of history behind it.
