I bought a 2019 F-350 dually with diesel, 4:10 rear axle King Ranch and just returned from a 4400 mile trip. Our DRV weighs 21,080 lbs. all up we weighed CAT scales at 30,040 lbs. We cruised at 65 - 70 mph and spent a lot of time in the western areas of Idaho, WY, CO and MT . My trip meter showed 9.2 mpg for the total trip. We drove about 600 miles without the trailer, I used to have an FL60 with a Teton that we had for 6 years and 185,000 miles. I would not go back due to the superior brakes, power and comfort. The F-350 would pull 5% grades in sixth gear at 2100 rpm on cruise and with the engine brake on and adaptive cruise actuated it would hold the same grade down on the preset speed. The combination of the MorRyde hitch and suspension I have nothing but praise for the handling of this package. My Teton also had MorRyde it sold me on the suspension, I never had any repairs done to the suspension in all those miles. I do have a Stealth module but only engaged when empty is it in play, position 3, I saw 17.4 mpg playing in the mountains with just the truck at the speed limits in Yellowstone and Jackson Hole
