Have the '07 D'max, Crew, 4WD, with the 5er in the signature weighing about 14,000 depending on the trip. This last one was a little heavier for the 9 day haul and we towed on level ground from Minot, ND to Thief River Falls, MN, then to Detroit Lakes, MN and home. Needless to say a pretty flat run with temps in the 70's. Got right around 11.5 at 60 MPH (MN 55 MPH Limit) and dropped to 10.2 in ND running 65. Didn't have much wind the whole trip, so not a factor in the mileage. Normally run around 18 empty down the highway at 65-70 MPH.
