Average gas mileage on C class

We now have a 32' fifth wheel. We get 10 miles pulling. Thinking of downsizing to C class (about 30'). Hoping to get at least 10 miles to gallon. Have any suggestions?

On a recent trip (1,800 miles) I was getting 16.3 MPG. I usually get 15+ but since I was traveling with a friend towing a 5th wheel, we had to keep the speed to 60 in California most of the way. On one tank I actually got 20.3MPG. However, I have to say there was a consistent tail wind the whole time and my friend went from 9.5 to 11.5 on his Dodge Hemi V8, so it wasn't just bad math. This is the first trip I have not driven 70-75 mph, so I could really see the difference. I figure in the 50,000 miles I have driven, I saved about $10,000 in fuel cost. Well, it will be somewhat less now as the turbocharger is a no-show and I have a feeling repairs are not going to be cheap. What is the real cost of an RV per mile? Anyone who just put six new tires on knows that is isn't just how far you can go on a gallon of fuel.

Wow hold on a second. 15 mpg nobody else gets more than 11. how are you getting 15


The Solera is on the MB chassis the same as my Winnebago View is and I have gotten 16 MPG on it. Towing my Subaru I'm down to 14.5 to 15.

Some consider the Leisure Travel Vans Unity a Class C. Over the past year and 17,000 miles we averaged 15 mpg pulling a toad.

Correct me if I'm wrong, but don't many, many signs along many, many California freeways/highways/roads state something to the affect that trucks are to travel at 55 MPH? If so, I sure wish they would - so that I could - in my RV.

P.S. I think that an RV is big enough in the rear so that even a legally blind driver isn't going to rear end it. At least my Class C has a rear profile that large. :C


The legal speed limit in California for big rigs is 55, towing a trailer 55. BIL complains every time we head to the races. Do they do it? Hardly.
It's 60 mph for semi trucks in a 70 in Michigan. A cousin of mine died driving into a semi truck on the freeway in CA. I've been rear ended before. Once on my bike flying through the air looking at the red light. Everyone has their own opinions. I still find it a hoot that 62 is considered too fast.

My RV does! ๐Ÿ™‚ It is so old (1990) that there is a square box around "55" on the speedometer. ๐Ÿ™‚

8.5-9 generally. We have had had a few tanks at over 10mpg. No winds, no hills, drive 55 and under.

This is the only place on earth where you get accused of driving too fast going 62 mph in a 70. LMAO. Justify anything you want by driving 55, I'll at least keep up with most of the truckers. I learned to drive in LA traffic. I've personally seen too many people rear ended to want to end up as a hood ornament on someone else's grill.
