I'm with you! I delivered a 30 boat for a friend Saturday with mine. He drives a 2500 Silverado gas(hog). He was scared to tow it, with his Chevy. I doubt if boat and trailer weighed over 10,000 lbs, probably 9,500. Filled the tank before we left, 75 miles later, when I dropped it off, EVIC showed 16.7 mpg! HaHa, my last hemi Ram would struggle to get 16 mpg empty. I reset mpgs on the EVIC and went on a long trip. Now , it has climbed up tp 35.3 mpg! My friend couldn't believe how easily it towed his boat up the hills.
