i have a 2017 f250 6.2 gasser with 3.73 rear end bought new. our first TT was 33ft approx 7500lbs loaded to camp. kept it year and half then bought a 38ft TT approx 9500lbs loaded to camp. i have put 37k miles on the truck. probably 1/2 that towing. up and down east coast mountains to the beaches. i have been very happy with it. the biggest advantage over my older f150 that i pulled the first trailer with is heavy duty suspension, etc. huge difference. the f250 pulls it solidly with almost no sway on open highways, plenty of horse power even in mountains. loves gas stations but no getting around that regardless, and maintenance and upkeep is way cheaper than diesel. at the time i bought mine, f250 trucks were priced about the same as the f150's
