I have 2018 KR 3.0 FX4 with 3.55s and I have also been impressed with the towing mpg's on my truck, as well as all around mpg's. I'm very happy with mine, and now with over 17K miles have noticed even better mpg's the past couple thousand miles. I'm not sure if those better mpg's are coming from the engine breaking in more, or if it is because of the new tires I put on in that time period, possibly a combination of both.
I can say that the tires I put on LT265/60R20 Michelin Defender LTX did not cause me any adverse hit at all on my mpg's--I'm sure they improved my mpg's over the stock P275/55R20 Goodyear Adventurer Kevlar that I took off. In fact, since I changed over the tires I am at 24.4 mpg average and the first 15K miles on the truck with the Goodyear's I was at 21.9 mpg average.
I have a long distance fishing trip coming up towing my Ranger Reata 1850LS boat, so I will post my mpg results after that trip.
