We pull over 16,000 lbs down the road in a fifth wheel RV. Since taking delivery of the truck in September of 2020 we have pulled over 36,000 miles from South Tx to the Canadian border in Montana over every mountain pass in between without issues while maintaining the speed limits and passing diesels sitting on the side of the road with steam coming out of the hoods.Part of the issue with any truck that one wants to pull loads with is they select the wrong gear ratio for the rear end thinking like the old days that a high ratio will get them better mileage. Not true.The new transmissions are computer controlled and adapt. My cousin bought the same F-250 I did but he bought the 3:56 gears as he doesn't pull much now, but anticipated buying a RV in a year or two. We get exactly the same gas mileage which is about 13.3 combo city/highway, mostly highway. With the specifications that Ford puts out, he lost many thousand pounds of towing capacity with that higher gear ratio.Determine what you want to do with your truck and size it accordingly. Personally, I'd never need nor want a diesel for our requirements. Your requirements may be different.</blockquote>
