Stop in for a cup of coffee

Yup...my 92 D250 diesel cranked along at 17mpg whether it was empty or loaded above the cab with hay bales.
the newest vehicle we have is a 2015 2500 denali with I think a 6.6 duramax. that thing gets 19 towing and 27????? I think around town. pretty spunky too. (for 7,700 pounds)
