I have had both, a 36' gasoline with a V-10 Ford engine that would get 8-9 mpg and now I have a Caterpillar 3126-E and it gets about the same as the gasoline mpg. But diesel is cheaper then regular gasoline at the moment. It could change.

One real important thing you should keep in mind is "most people lie about mileage" and a lot just don't know the truth because they don't calculate it properly or they can't.MH on different angle,foaming etc.Forget about mileage or buy a smart car and camp in that.

Hi Jennifer,
It so happens that I have a very good friend with an '01 Journey 32' with the same Cummins ISB and 5 sp Allison transmission that is in the motor home you linked to. He gets 10-12 mpg regularly. He drives 60-65 on interstates. The ISB is widely known to be the most fuel efficient diesel being used in motorhomes. The 5 sp trans is a compromise and you would be better off from a useable power standpoint to have a 6 sp but I would not consider this to be a deal breaker. You will be slow up hill while towing but you will get to the top. Winnie builds a quality, well engineered motorhome. If you make an offer on this Journey, make sure to include a complete service on the engine, transmission and chassis.
Let us know what you do & how it turns out.
Good luck & safe travels,
Steve O

42' DP, 330 Cummins, no toad, under 60 MPH and we average 8-9 mpg. I think you can use this for a ballpark figure in planning your budget and be safe.
I really like that unit. Congratulations on the selection.
Have fun.

I drive back to South Dakota from Northern Cal every year and I average 10 to 11 mpg on our 03 Fleetwood Expedition 300 Cummins diesel. The kicker is to not drive over 60 to 65 miles per hour and I buy the PRI diesel additive and put it in everytime I fill up. I do agree with the others that fuel for your coach is the least expensive aspect of owning a Motor Home, you have to look at the entire package.

It's nice to know what to expect in the way of miles per gallon but in my opinion fuel is the cheapest part of motorhoming and I would not put too much stock in the few mpg you may achieve one way or the other. The big expenses are depreciation and financing. It's better to just enjoy the motorhoming experience and ignore the few dollars difference you will spend on fuel whether its diesel of gasoline. JMHO

Thank you all SO much!
I can't believe I am actually starting to understand some of this stuff.
(Though usually with the help of my new Automotive Technology textbook.)
; )
Thanks!
