Since this seems to always be a topic that comes up, figured I would post what I've recently seen for mileage on a couple of trips with the new 6.7.
Went 2500 Miles RT from MN to MT and back. Towing an empty deck over 8x10 trailer (aluminum) with salt shield. Kept at speed limits (70-75)
MN to MT - Empty - Averaged 14.5.
MT to MN, Two 700 RMK's (155/163) - Averaged 14.0
MN to IN to pick up a trailer in IN, 7x27 R&R with Triple axles. Stayed at speed limits - 60-65.
MN to IN Avg - 20.9
IN to MN - 14.4
Truck had about 14k on it for the trip to MT and just turned 20k for the trip to pick up the trailer.
This is my first Ford, former GM guy and overall still extremely happy with the truck.
