jleamont Report post Posted July 5, 2021 (edited) Paul, sounds about right. I had a pickup with that engine and it was consistently at 9.6 - 10.0 mpg empty. Much less vehicle than what you have, same power train. we had a Coachman Santara Class C before the DP we have now and we never got more than 7.0 I even installed a Banks Power Pack, ran better didn’t do anything to the MPG’s.

wildebill308 Report post Posted July 5, 2021 That mileage sounds about right. Do you have the 6 speed transmission? Bill Share this post Link to post Share on other sites
manholt Report post Posted July 5, 2021 I have found over the past 54 years and 18 Class A's, there is not more than 1.5 to 2 mpg difference between gas rig or DP. Size, weight, HP and terrain is the average determining factor! You found that speed (wind resistance) on a class C, makes a big difference in mpg! Sit back and enjoy the ride, at a slower speed, you'll also get better road manners. Share this post Link to post Share on other sites
