What mileage does a 2017-2019 F350 SRW with stock gearing get towing a 36 foot 5er that weighs 15K at 65 MPH on flat roads, no wind ?
When I had a '15 F350 SB, 4x4, cc, 50 gallon Transferflow replacement tank, 3.55 gears towing a '06 5er weighing 12,800, I'd get 9.5 or so at 70 mph. Same truck towing coach in sig weighing in at 16,000, I dropped down to 9.0 mpg's at 70 as well. Now w/ my 17, DRW in sig I'm down to 8-8.5 @ 70 biggest diff is 4.10 gears, 2 extra tires and longer box. Same truck putzing at lower speeds sightseeing and all, will jump up to upper teens.
