yeah I'm not sure what you guys are doing but my last trip up to the cabin I got around 20.5 mpg.

No trailer, polaris sportsman in bed. Doing 55 to 60 for 700 miles. I got a 3.55 rear end though and I'm not knowing for hammering on the throttle. I like to let the truck eat at the hills.

Lol, true. I’m a single rear wheel cc short box.

I kinda wished I would have ordered the 3.31 but I guess 3.55 will be good when I do tow my triple axle 21k gooseneck

I just drove from Central Wi to Central Fl and back last week. Was empty going down averaging 75 mpg. I got 18.5 MPG on the computer after 1400 miles. Coming back slowed down to 72ish towing a 16' enclosed empty motorcycle trailer and got 13.7 MPG. Over the summer did a 3200 mile trip to Wy towing a 33' 10,000 lb 5th wheel and averaged 12.0 MPG.

My last tank was all towing, up to 8000+ feet and back to 4300 feet. Towing a 6000+ pound TT and a lot of idling (hookup and disconnecting). 20% driving through the city, stopping to shop on the way home. I got exactly 12.5 mpg hand calculated. I think that without all of the stop and go stuff, it would have been much better? The lieometer, said 14.6 mpg. Hand calculated is the only way to know for sure. It seems that these trucks get around 12 mpg when towing. I’m happy with that.

I've been getting a steady 15 mpg around town and 16 to 17 mpg hwy depending on speed. 4.10 gearing keeps me at 70 mph max on the hwy. Towing our close to 17K pound 5th wheel I usually get 9 mpg @65 mph. Not bad for a DRW with the 4.10's.
I have a 2018 F350 6.7 diesel, with the 4:10 gears w/ electric lockers front and back. I put in 51 gal drag up tank w/ tool box, with aitlift air bags; b&w companion hitch, and new tires for off toad and I pull 16k 40’ 5er. In town running round I generally get about 11-13! On Highway it’s was dueing 18, but pullin trailer my trailer up hill 4-9, down hill, just use your imagination! Wouldn’t take for my truck!!!
