I've had a tank as high as 14mpg going 75 with my 8k lbs travel trailer. 98 dodge 24v 5sd. Most tanks at 75 were in the 10 to 12 mpg with the cruise set to 75. I want to try it at 60 to see if I can get better than 15mpg. Kinda hard for me to drive that slow. Feel like I'm going to be run over by a semi. My truck empty can also top 20, but it rarely does bc of my fat right foot.
