We tow a new 17FQ Viking and get about 12 mpg at 55 mph. If we go 65 mph we get 10 mpg. The problem. I love the truck for towing and have gone through the Appalachians and never had a problem. Next year we are going to the Rockies for 5 or 6 weeks.
This is a 1/2 ton truck, I do not expect big diesel performance.
My crappy mileage was 10.2 mpg at 60 mph, and 8.5 mpg at 65 (cruise control).
I can't drive 55.....
