    When NOT towing, does the tow package (3.71 axle) impact gas mileage? The window stickers don’t change, but I’m wondering what the real world says. I want the tow package but not at the expense of significant drop in mpg. We won’t actually use it to tow that much, just thought it would be a “nice to have” since we’re boaters and have several boats, you never know if/when you might have occassion to tow with your SUV as opposed to your truck.

    On the highway I average 20-21 mpg cruising at 70.

    '19 Shorty w/ tow...I'm at about 19.3 for a 1000 mile trip I just took from MPLS to KC driving about 8 mph over on 87 octane and mostly in ECO mode. 9,900 miles on mine and lifetime avg (on Trip 1 which I have made my 'never reset' one) is, to me, a disappointing 18.8.

    I notice about a 1-1.5 mile increase in ECO vs. Normal on my 600 mile trips for work on freeways.

    Wow 18.8 is disappointing...what were you expecting? Thats pretty nice for a 400hp 6k lb 17ft long luxury block rollin on 22 in wheels with a heavy duty axle turnin underneath it. Most new crossovers only get 20 or 21 mpg avg

    I guess it's all relative. I didn't buy this vehicle for the mileage, but having an updated diesel offering (not the current 3.0 PowerStroke) would be a nice option. The new 3 liter straight 6 from GM has my attention based on some of the videos I've seen on TFL (34 mpg running empty at 70 mph for a 2wd model). If GM offers their new 3 liter diesel on the new Tahoe/Suburban, Ford is going to have to step up to the plate with some alternative powertrains for the Expy. I thought I read that the new UAW contract with Ford discussed a hybrid Expy at some point in the future.

    Here's what mine did on a trip my wife and I just did. We ran all over getting things for her, and a bunch of interstate and some idling and I think its great milage myself. This is a tow pack 4x4 Max loaded completely full of stuff we picked up for my wife.

    I took a 3000 mile trip right after I bought mine. Shorty Limited with tow pkg. Averaged over 23 for the trip running about 5 over posted limits. 24-25 indicated on trip computer. I’m good with that.

    I average about 19mpg for combined driving. But I like “exercising” the turbo. :emotions33:
