You don't drive & own one of these traveling earthquakes for the MPG. You do it for the freedom & ability to see our beautiful country. I've only worked up my MPG once in our 5yrs. of fulltiming mainly because it is what it is.

Hey Shaky,

The prices are high here in California for sure! But your mileage claim at 5mpg is laughable, or your filters are bad!!! I get 7 to 8 all year long here, unless I"m pulling grades all day long, and I don't know anywhere you can do that????

Last weekends trip to Newport Beach from Palm Springs, with our 4000#+ Jeep Unlimited in tow, we averaged 7mpg running 60 to 65mph on the Scan Gauge.

Regards, Hamshog

Amen to that. When people ask me what kind of gas milage I get, I tell them if you have to ask you can't afford one.

Wow..7-8mpg. That's fantastic. I have a 2011 geotgetowm V10 with 14k miles. I do not tow or load up the rig and drive between 60-65 miles an hour.. Lie-o-meter on the dash says 7-8.. But in reality im around 5 sometimes 6 miles per gallon and that's Florida flat land..

I can't see how the same engine would get wildly different mileage between two drivers who both drive the same speed.

I don't believe anyone gets any different than near the stated 7.5mpg average if they drive around 60-62 mpg on the flats.

Perhaps a more aerodynamic shape or a lighter rig might make somewhat of a difference.

The styling of the coach will make a difference. The biggest difference is driving style. I get better than average gas mileage. I do not floor board it on hills. I try to go "easy" on the gas pedal. I traveled out west in 2008 and 2009. both trips were over 6000 miles each. I averaged 8.32 mpg on one and 8.33 on the other. I was towing a Honda Civic.

Just got back from trip to Apache Junction, AZ. 756 mi round trip averaged 7.5 MPG, 60-65 MPH not towing. Very strong head wind from Desert Center to Banning on I-10. Slowed to 55 MPH, even most the trucks slowed to 55.

Our old Safari Simba 33' with 8.1 gasser gave a reliable 7.5 on a 6000 plus trip towing a wrangler.

Testing by Cummins (obviously on diesel engines) with fleets of units and drivers show that the difference between the best and worst drivers is 30% even when driving the same rig.

I run fairly heavy for my rig, normally 20,000 - 20,500 with full water tank (90 gals) when not towing. Normally average 7.5 @ 60-65 MPH. Get the same when towing, because I run at 55 MPH.

I agree with others that don't worry about gas mileage. It's a one bedroom condo/box going down the road. There are way too many variables, terrain, wind, traffic etc. There is not much that can be done about MPG, if you want to go from point A to point B it's going to take gas to get there. If you only want to get 8.5 MPG drive from Palm Springs to Phoenix. But you can't drive back to Palm Springs without it costing you some MPG due to the wind. It's just not important to me. We're suppose to be enjoying our retirment/vacations.

Our '85 Class C with a 460 (carb) got 6 on a good day at sea-level and only about 4.5 at altitude (of which we have quite a lot around here). Our recently sold 2002 32' Class A with a fuel-injected V-10, got a reliable 7.5 regardless of altitude.
