    Undecided about whether to buy a gas or diesel engine. Could anyone provide info on fuel mileage for a 34 ft. MH with diesel engine? Have been unable to get this question answered. Am about a 65 mph driver. Thanks for any help given.

    I have a 35' Allegro Bus with a 230 cummins and get 10-11 mpg. Towing makes no differance. Mileage stays the same.
    Good Luck

    I have a 36' Monaco Knight with 315 Cummins. I get 9-11 MPG depending on terrain (mtns vs flat). Mpg is best in highest gear , just abve the shift point. For me it's at 1500 rpms or 59mph. You do NOT want a 5 speed trans.

    Travler, you might find that you get better mileage at 60 than 65. Gas or diesel. There has been a lot of discussion on that subject and most have come up with a point where they get the best and in a lot of cases it was in the 57 to 62 speed range or an rpm like dawright42 said his at 1500. I drive a gas and mine is at 2000 rpm and also 59 mph.
