Small and light gets the best fuel mileage. You looking for a class A, B or C?

I get 8 without the Gear Vendor on - 10 to 11 with it on. Didn't know any such thing existed until I got my Itasca with it already installed. And I love it! I unloaded half the stuff in my RV - things I had carried around and never used. All I have with me now is a small grill, one bike, a few tools, two lounge chairs, outside lights, the chemicals necessary to maintain the exterior of a rig and a few pieces of fishing gear. Inside, it's just clothes, linens, books, the usual domestic necessities. So I'm hoping to get even better gas mileage.

We just completed a 22 day, 4,399 mile trip, using 407.562 gallons. Our GVW is 22K pounds but our actual traveling weight is around 19.5K. We have a 275hp Cummins ISB with a 5 speed Allison transmission and pull a 2,300lb Saturn toad. I suspect that we are in the top end of the mpg for MHs.

Within our results, is a drive the length of Illinos where we maintained 55mph - the speed limit for MHs there. It was over Labor Day weekend the there was significant police activity the entire distance. While doing that, I discovered that I can save almost 1 mpg traveling at 55mph versus the 63mph that I normaly use. 63mph gets significantly better mileage than if I try to go 70mph. It takes a lot of energy to push a big box down the road. The bigger and heavier the box and the faster you try to push it, the more energy it takes.

I've seen reports of 6-7mpg on the very big and heavy rigs. We were parked next to a 42', 58K pound Country Coach in Nashville and he said that he averaged 6.5mpg. A buddy of mine with a gas rig claims around 7.5mpg. Even with the differential cost of diesel fuel over gas, mine is cheaper to run than his, given the same trip for both.

It really, really, really depends on what you want/need -- what you need the "motorhome setup" to do.

- A tiny rig with a very small engine would get better mileage than my 40' diesel, but it wouldn't do what I need my RV to do.
- My 40' diesel gets better mileage than a 40' gas rig would, but there are a lot of other factors involved too.
- Any motorhome without a heavy accelerator foot will get better mileage than a comparble motorhome WITH a heavy accelerator foot...
- On any rig, the less weight you carry the better, so don't take along anything you don't really need.

If you can provide more details as to what you are considering, and what you want/need a motorhome to do, you will likely get more useful answers.

Finding a motorhome that gets good fuel mileage is like finding the cheapest fuel. Some are a little better but none are good.

Smaller motor does not necessarily mean better fuel mileage, a motor running outside its peak power band can easily burn more fuel. The smaller motors also have to operate at a higher rpm when climbing hills, burning more fuel. If you travel mostly flat lands you will see an improvement in fuel economy, but hilly areas will cause constant downshifting killing fuel mileage.

You might want to check into motor homes built on the Freightliner FRED (FRont Engine Diesel) chassis as they claim after, engine break-in 12mpg.

Damon has a new 31ft coach, the Avanti built on the Workhorse W16D chassis powered by a MaxxForce 5 200hp v6 diesel that puts out 440 lb ft of torque. It should do even better fuel mileage wise.

You can see information on the chassis here:

I have a Class A DP with a 5.9L ISB and get a little over 10MPG towing my car. My MH is fairly light weighing about 20,000lb loaded. If you want to get more MPG look at a Winnebago View or a Class B on the Sprinter chassis. The View gets 16-18MPG and the Class B-Sprinter chassis gets 20-23MPG. Those who already own larger MHs tend to keep them and use them. If your are considering buying one your choices are difficult. At current fuel prices I am still comfortable at about 10MPG and would purchase a MH with that MPG.
