We had a 24' Class C on a Ford 450 V10 and got 9.5 to 10.5 pretty consistantly. We also keep the weight of 'stuff' to a minimum.
We had a 29' Class A on a Ford 550 V10 and got 7.5-8.5 with an avg of 8mpg
We now have a View and get 15.5-17 MPG.
It was mentioned to us that diesel cost more so it evens out.... so what was the point of downsizing to save fuel?
First it wasn't the only reason we downsized. Second, I did the math. Even though Diesel costs more we still save 40% than the Class A. It isn't about the money as much as the fact that we are using less fuel....ie: cutting our dependency.

My 55 gallon tank is VERY DIFFICULT to fill up to the same point with each gas stop. I cannot go by the automatic stop on gas station nozzles. The only way I can consistently fill it back to what I think is very close to 55 gallons - and hence get consistent values for mileage calculations - is to trickle fill my tank until just short of spilling gasoline out the top of the fill tube.
This takes around 10 minutes longer to fill up and can only be done with some fueling nozzles. If I don't do this, my tank is never full - maybe only around 49 or 50 gallons in it - and it most likely gets filled to a level that varies plus or minus 1 or 2 or more gallons with each refueling ... depending upon the shutoff control's sensitivity for any given station's fuel pump nozzles.
Good point. It took a few more minutes to top mine off from 50 gallons to 54 gallons. We've only done three trips in our Jayco 31SS with the V-10. I don't know what gearing it has. we tow a 7x16 enclosed trailer with dirt bikes, gear, tools and a 53 gallon fresh water tank. The first trip I hand calculated 5.7 MPG, but don;t think the tank was fully topped off to start. The next trips were between 6.5 and 6.9 MPG. I used the tow/haul mode less, so it would up shift a little sooner on the highway and I think that helped. I drive 70-75, most of the time, so I figure my mileage could improve alot if I slowed down. I'll probably install a programmer to help with getting over the hills. We drooped to 45 MPH in a couple places last trip.

I get 20 mpg on my 31 footer...some times a little more...depends on how steep the hill is that I'm going down...going back up is another story...always seems to average out about 8 mpg no matter what speed I drive and I never drive over 60 mph trying to conserve on the gas consumption...I'm always towing a trailer loaded with either 2 snomobiles or 2 atv's...I don't travel without them... Maybe i could get my mileage up to 8.5 or 9 if I weren't pulling my favorite toys..

My nephew drove mine 1000 miles at 60+ and averaged 10mpg-Knowing him if he says 60 its more like 65-70-he kept good records and it was 10,with 15 gal still in the tank when done.Some cards offer $.05 rebate on fuel charged,charge on your B.O.A Mastercard and get flyer/hotel miles,the same with A.E card with the bonus of Home Depot miles.

Just got baack from 1st trip with our new Coachmen 2130QB w/ 6L Chevy. We did Shenadoa Pkwy Blue ridge and Smokies. Last 2 tanks (which included Smokies) were 11.5 and 11.7 mpg.
If you don't keep your tires properly inflated for the REAL load why would you expect them Not to fail?
- Damage done to your tires is irreversable. Puting air in tire that you ran underinflated will NOT fix the damage you did.

I watched a show on TV a while back "How things are Made". This particular show featured fuel tanks from the big three. The tank and fill tube are designed to fill the tank to no more than 80%. This is to allow for the expansion of the fuel in warm weather. I suppose different gas stations are not always level so you get some variability in your fill up. I think this might account for the different values we sometimes get when we try to calculate the mileage from fill to fill.

Our 2006 Winnie Outlook 29B with two slides and Vue toad runs around 7.5-8MPG. I attribute it to weight, since we are close to max. I drive between 55-65MPH. It shocked me that the price of gas ahas MORE THAN DOUBLED since we bought the rig. Hopefully, a new government can figure out some relief.

Vic K was probably quoting Imperial gallons which are 25% larger than US Gallons. Thsi translates to 10-11 mpg south of 49 - about 1-2 mpg less than I get in a 25' Citation with a 6.0L GM V-8 (level ground, 60 mph).

1989 29' Tioga Class C; 5 in the hills, 9 on the flat; always 60mph max.; It's quieter, smoother and saves on gogo juice
460EFI, but NO overdrive; wish I had it.
As far as class A vs. class C... the REAL benefits I can confirm are:
1.) you're almost always sitting in the shade - I like the overhang.
2.) easier to get in an out off.
3.) when you need repairs, almost ANY shop will work on it... it's just a van... now, it might be to tall to get into the shop; but they're never afraid of working on it. Friend of mine as a $300k Class A; and when it's down, we spend a day trying to find someone to work on it and another day getting the parts... I can get all my "van" parts at Orileys or the like.
