2003 8.1 vortec mpg generator#
With generator running both a/c units on and the wife cooking it looses about 1 mpg. In any event I drive around 67 - 68 mph in low side of power band and get 9.5 miles per gallon without the generator and all water/holding tanks empty. I just didn't feel it was worth the risk as the semi who decided not to let me pass was not up to the task.

Now I am trying again to get more specific information.Ĭan people just please reply to this post with what kind of motorhome, length, motor, tranny & their mpg? As much detail as you want to give. I asked a while ago about what motorhomes get the best mpg. The Allison is the tie breaker, IMO.How Many Miles Per Gallon Does Your Motorhome Get? We found the Ford’s extra two cylinders only served to use more fuel but made no extra power that we could actually discern and naturally two extra cylinders is more parts go bad. However, if the Chevy has an Allison behind it, many do, then that is the much better choice IMO. Never had any issues with either to speak of. We used the Ford and Chevy in commercial service and found they were essential equal.

This all may be a moot point as he may have it sold this afternoon.
