On my last trip I got a hair over 14 mpg with my CTD, but we were coming down outta the mountains. Still climbed some hills, but overall we were descending. We tow around 65-68 mph. I'm pleased to get 13-14 towing at those speeds with a 32 foot long 8500 lbs trailer.
Empty on the highway I got almost 22 at 75 mph... that is amazing to me. Combined driving (mostly red light to red light to red light around us...) I am getting 17.5 to 18. Again, for a 7500 lbs truck, I am very pleased with those numbers.
