Too many variables here.......driving style, terrain, wind, etc. But, with that being said, expect a drop of at least 2-3 MPG from your normal driving.

I loose between 4-5 mpg towing my 4 seat maverick on a 14’ aluminum single axle trailer with my 350 6.7. I learned to just deal with it, it’s a shocking loss considering I can tow my 37’ 13,000lb fifth wheel and only loose another 1 mpg from the SxS. Oh and I don’t drive fast, set the cruise at 70.

This is the lifetime average with lots of in town driving and some heavy towing. Straight highway driving it averages 15-16 mpg.

And.........if you are truly worried about fuel mileage, set the cruise between 55 and 60 and tell the world to kiss your azz. Forget 70.

Not totally worried about fuel mileage but this going to be the first Super Duty that i have purchased (the others were work trucks with work gas) so i kinda want to know what to expect. I see posts from time to time wher heavy towing MPG and 34' travel trailer MPG is discussed but never seen a post about a moderate to light load. I dont tow heavy, and i dont do much in town driving. most of my miles are back and forth to deer camp (500 miles one way) on the high way, and an out of state trip (1000 miles one way) a couple times a year, just curious as to what to expect MPG wise.

Your average will be better than mine, I have 50% ish in city mileage which is terrible, drags the average down a good bit. I try not to worry about it any more, keep track of it more for interest than anything.

One thing for sure is it is not even close to the mileage my 2015 Duramax got. Not even close...love the super duty truck so much more that I’m willing to sacrifice the mileage.
