Even though I'm legal with my 350 dually pulling my 42 ft TH'er, I still put air bags in the rear. I would highly recommend this to anyone pulling a heavy load.
i got a 17' F350 long bed, care cab diesel. I straight piped it, put in a Live Wire tune and cold air intake. Its absolutely sic. pulls trailer at 90mph and still get 14mpg. no trailer pushes up to 19 mpg driving like a retard. yes Ford is pure badass shit
Must be nice to not have to worry about a warranty. Keeping my '13 totally stock until '20 when the extended warranty runs out.
This is a double edged sword and I compare it similar to a cell phone plan. Ford, Dodge, & GMC know the DPF/DEF/EGR systems murder the longevity of their motors. Check online at the used newer stuff with higher mileage at the end of it's warranty, fields of trucks. The platforms are strong and I'd be willing to void it after a few years of any teething issues if I planned on keeping it.
