We have an older one with Cat 330 HP on 40' coach with toad. Last year 7K miles traveling through the midwest, northwest and southwest averaged 7.6 MPG. I was happy with that. I estimated that I would get about 7 or less. I set the cruse at 65.

I have a coach that weighs about 40K lbs (20 tons) - 2001 Wanderlodge LX. It has a Cummins ISM (500HP version) and I get about 7-7.5MPG. I generally drive it about 70 or so on the Interstates.

2005 35'with a Cat C7 I get about 7 and pulling a 16' enclosed trailer doesn't seem to change the MPG by more than .5 MPG. I just got setup to pull my 07 Tahoe before the world ended and haven't got a chance to pull the Tahoe yet.

True. Any RV is an investment, literally, in the expenses of this lifestyle.

We've had our FW for 10 years and maintenance is a huge factor. We just invested $1700 in new decals and that does not include the labor.

I have a 2004 Cat C7 350hp - 40 feet. I get between 7.5 and 8 pulling a toad. This is out west - lots of mountains.

With the weight the engine is pulling, I figure that is not bad.

Seems that everyone always gets better mileage than me, no matter what I'm driving.
I'm an easy driver too, with easy starts off the line and for cruising at 57mph and just enough to prevent downshifting into 5th going over grades.
I'm at 16tons and over a 13yr period, among three owners, my average is 6.2 on the OEM digital dash readout. I tow as well and was only able to increase this average by 0.1 over four years.
Not even sure, if this is counting the genset, since I don't know where sensors for this is.
I've also noticed that some of these big rigs, get as much as our toad, all by itself. Ummmmmmm!

Glad to hear from an honest owner. My Cat350 in a 40 footer and towing a CR-V gets 6.6 to 6.7. I thought mine was worse than anybody's.

But, I have to agree with the guy who said that mileage was way down the list in importance. Once you pay for insurance, taxes, storage (in my case) and other maintenance expenses involved, you'll see. Kind of like buying an airplane and worrying about MPG.

I certainly agree and these numbers are only good for the sake of discussion and for wondering if you have a leak somewhere.
Actually and I've said this many times, I feel that DPM (depreciation per mile) is where the real cost of ownership lies and the only way to offset that some, is for buying older.
We bought ours at 9yrs old and it's still gonna be a bunch of money, once it's all said and done.

I have a 98 imperial it has the 8.3 cummins. There are no electronics on this engine aand it is rated a 325 hp. I tow a full size Dodge 1500 pickup. On reasonably flat rd keeping around 60 mph. I can get 10 mpg easily. In the mountains it will drop to 8mpg. My last coach was newer and had the same engine with electronic fuel injection and the best I got with it was 8mpg on the flat and as low as 5 mpg in the mountains. Not a great difference but it does add up.
