Now that I have your attention, here's the deal. 2000 Tioga 22C on a Ford E350 chassis, 2 Valve 5.4L engine, 4R100 tranny and 4.10 geared Dana 70 HD.
Last summer took the family on a 3,000 mile West coast road trip. I averaged 10.5 MPG for the whole trip. I averaged between 65 and 75 MPH and climbed many grades in Oregon and Washington pulling a 14' Gregor fishing boat packed with all the boat stuff and 4 bicycle's.
This last week we went on a 1,006 mile trip to S. Utah. Pulling my trailer full of dirt bikes and riding gear and reducing my speed to 65 MPH max with most time spent at 62 or 63 MPH brought my average MPG up to 11.5 MPG. In my opinion, if you ran 55 mph, you might get 12.5 mpg. Heck, if you drove 45 mph you might even get 13.5 mpg, thats if you ever made it to where your were going! LOL
There are people who will profess 15 or 16 MPG or better from a GAS engine MH, I don't know if I buy it. I think anyone professing any MPG figure, should be required to run a minimum of 2 tanks of fuel to post a MPG claim(?)No Scan gauge claims, real miles with real gallons type of claims
So the bottom line folks, there are MPG's for the taking. You just have to back it down a notch or two on the speed, let it scrub speed on small hills, use downhill's to get a little run at the next hill and so on. I think keeping it between 60 and 65 MPH is the sweet spot for fuel economy and a decent average speed.
So lets hear your real world figures.

You AVERAGED 65 to 75 mph over 3000 miles in a class C?
I can't average more than 65 mph over 550 miles in my wife's car, running on roads with 70 and 75 mph speed limits, with cruising close to posted limits. That's a moving average, per GPS tracking; not counting any non-moving time. This has been pretty consistent, four trips in the past two months, same roads, same car, back and forth to the cancer hospital in Houston.
In my C I average, over 200-300 miles, about 50 - 52 mph, with cruising speeds of 60 to 65, on those same 70-75 mph speed limit highways. That's also from GPS tracking my moving average.
To average 75 mph, you will have to cruise at about 85. With the winds I usually encounter, my C won't even go that fast.

To accurately determine average MPH is take the mileage driven divided by the exact time it took to do it, including stop lights, etc. You can use a GPS, and you'll be fairly accurate, but actual numbers is better. Eliminate fuel/rest stops from the formula, use only times traveling.
Also, to accurately determine fuel consumption, drive to the gas station, fill the tank, and start your miles and time calculations from there.
As I've said about a thousand times here already, if you want to improve your mileage in a house, there are only 2 things you can do-
1) Make certain your routine maintenance is current (oil change, tune up, front end alignment, tire pressures, etc.)
2) Run a vacuum gauge. Once you learn how to read it, and see just how poor a driver you really are (and you will!), you'll re-train yourself in the fine art of driving efficiently.
Will you then get 20mpg? No way! It's a bloody house, for crying out loud!
My bad, I should have wrote "moving average". My GPS stops the clock when its not moving. If I tried to average out the speed also counting the time stopped for fuel and fireworks purchases, my average speed would probably be in the 50 MPH range.
Anybody did a real world MPG with and without a Banks system?

I just took my first camp trip with my 96 24 foot e-350 ford chassis with the famous 460 guzzler with EFI. from Vacaville, Ca 125 miles up the hill to lake tahoe, and then down the same hill . from 400 foot above sea level to 7000 feet above sea level, and back. kept the speed right on 55 both ways, and recorded 14.6 mpg. The reality is that I probably got 8 mpg going uphill, and 16 mpg going downhill. but the fact is that when I got home the average based on my tank refill......14.6 mpg
I have reduced my driving speed from about 70 to about 55. I don't work it on the hills. I have gone from about 8 to 8.5 to 10 to 11 depending on the terrain and City driving. Right lane freeway steady 55 is best. A couple of miles per gallon improvement on an 8mpg is 25% which is pretty good. Best thing though is the driving is so easy and much less bumpy. I arrive so much more relaxed and not subtantially later. Now really want to save real gas-drive a toad that gets good mpg as you will drive many more miles in the toad. I tow a Prius on a dolley and if I drive the way I am now driving the motorhome I average around 55 in summer months. Winter is less as heater works off gas but air runs on the electric. Changing our driving habits by planning even short trips around town better, walking more, using public transport when available and inexpensive may be tougher than quitting smoking but if we want to save fuel that is the best way.
