I don't worry about MPG, if I want to take my house with me. I just like to keep track of it to monitor the performance of the house. If I worried about mileage I would take my VW Passat diesel 49 MPG. But then we would have to sleep in someone else's bed.

I just completed my first long trip in my (new to me) class A. We did 6500 miles from CA to MA and back. Based on the odometer distance, I averaged 7.0 MPG. I found that my odometer mileage is consistently low compared to the miles on google maps - If I adjust for that, I averaged 7.2MPG... No toad.

On the flat land between my home in the Piedmont traveling to the South Carolina beaches, not pulling our toad (best case), I see 7-8. If I head to the mountains, or pull the toad I see something like 6. Yuck. Mountains pulling the toad and M1 Abrams do better. I'm running a 1989 HR Imperial, P-30 chassis and a 454 ci 3 spd auto. Those old gasser big blocks humping 18K plus are a global warming junkie's wet dream (or nightmare). I still love my ole girl.

FUEL ECONOMY IN A MOTORHOME! I don't even think about it, if you need to ask the fuel economy you can't afford a moho. The whole idea is recreation and fun, some spend their money in a bar, some in a casino, others on hookers, do they worry about the economics of it all?

Funny but I am more interested in range. That way if I have lots of range I can watch the prices and take advantage of cheaper prices.
I hate stopping to fill up.

Out of 48 posts I have concluded that we all get around 7 to 8 miles a gallon unless you have 100 miles of uphill or 100 miles of downhill which certainly will have an effect on your calculations.

I to am more interested in range, and I really don't like to stop for fuel, but I try to fill up when down to half a tank. The in tank fuel pumps tend to get hot when the tank is low on fuel. They need the fuel to stay cool. I have had Motor homes that vapor locked on a hot day and low on fuel when the pump got hot. Never want to run to low on gas and if a fuel injected engine if you run out of fuel it can be a expensive proposition for the injectors.

In my old rv with the 460, I got 6. Less if climbing. More if going downhill. But usually averaged 6. If I was towing a 300lb trailer, I averaged about 5.5

In the rig I have now with the 8.1 workhorse and Allison tranny, the idiot computer tells me I get about 8 to 8.5, even more if I drive carefully. My calculations at the pump tells me that I get about 7.5 or about 6.5 if I tow the same trailer

That being said, my old RV was a 26ft 1989 class C weighing about 11,500lbs. The rig I drive now is a 38 ft Class A at about 22,000lbs.

I am pushing a whole lot more weight and getting just a little better gas mileage.

That being said, it burns what it burns. I have never backed away from driving the rv because of the gas.
