Average gas mileage on C class

[mema_poppop]

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?

So in summary:

If you have a Class C gas engine expect 7-8MPG at legal speeds
If you have a Class C Diesel engine expect twice as good at 15MPG average.

Have a 32-ft. Jayco Greyhawk with the Ford E-450 V-10 gas engine. It gets 8-9 mpg running 60-62 mph with no toad.

32 ft ford e450 v10. 7-8 mpg probably closer to 7 than 8 towing a 18 ft car hauler with a polaris rzr offroad buggy and atv, and going the speedlimit +/- 5 mph.

My 1995 Dodge Scotty Diesel Cummins 6 cylinder does 16 not pulling a car trailer with my 40 Ford. Pulling the car trailer 12 driving 60mph. The best I got was 17.4 driving 50mph for 300 miles on the Natiches straight. I know I miss spelled it.The faster you go the mileage goes down as you know. I had a 2004 Chevy Four Winds 31 foot 6.0 and got 6 to 8. I sold it went back to the Dodge Diesel.

As long as you are doing the speed limit or the lowest speed allowed (which is posted), if someone else wants to go faster why would ANY one care if they are passed??

Truckers have been driving/passing for years and 9 times out of 10 even if you ARE going over the speed limit they crawl up you but and then pass.

Sorry, RV's are big, heavy, high profile and more importantly hard to stop on a dime. Towing a trailer and stopping on a dime to avoid an accident? Well we see the result of those going too fast jackknifed and upside down in the ditch all the time.

Just not worth it to me and more importantly I know it's not safe in the RV I am driving for myself and those around me.

I waited a LONG time to retire and go RV'ing. Certainly not going to go fast to keep up with the pack or to avoid another passing me and become a statistic or worse yet make some else's family a statistic. Just saying.

Your post above is the best one I've ever read explaining why us RV travelers (retired or not) can follow our instincts on what speeds to travel for ultimate safety, relaxation, and economy .... without feeling guilty about it. :C

P.S. The air above Mother Earth probably would appreciate us all driving a little slower, too, because slower speeds probably equate to less polutants per mile.

"boy is the ride rough in that far right lane no matter what part of the country you're in."

On trips to DC, using I-95, my wife won't drive in the right lane all the way there because it's so rough. 😄
Especially in So Carolina.

We try to drive in that lane too when in the RV .... HOWEVER .... boy is the ride rough in that far right lane no matter what part of the country you're in. Of course mile after mile on rough highway potholes, cracks, and joints is also hard on an RV's heavily loaded tires, no matter what the passengers inside might be experiencing.

We even prefer the far right lane when cruising along in our smooth riding family sedan, but that lane is so often in poor shape from all the big rig traffic that we avoid it even then.

8 mpg on our 24' e350 class c at 58 mph.

We average 15+ mpg with our 2012 Forest River Solera. We're pretty pleased with that mileage.

I posted earlier about getting 8 to 9 mpg at 62 mph, and 6 mpg at 70 mph. Since everyone is talking about speed, let me elaborate a little on my earlier post.

I drove from Memphis, TN to Yellowstone National Park, a distance of about 1600 miles. If I had driven 62, as is my usual, I would have averaged about 50 mph overall taking into account slow downs and gas stops. Since I drove 70 mph, I averaged 60 mph taking into account slow downs and gas stops.

At 60 mph average, it took me about 26 hours over 3 days to drive. At 50 mph average, it would have taken me about 32 hours over 3 days to drive. That is a difference of 6 hours, over 3 days. Or, 2 hours per day. To save that 2 hours, I spent about an extra $300 in gasoline, or $100 per day in gasoline.

Driving home, I went slower, I had learned my lesson.

We get just about 9 mpg and that includes some genny use.

Michigan freeways are by and large 2 lanes each direction. I'm not in any hurry either driving this big box. In any case it is a personal decision. Driving so slow as to cause all traffic to route themselves around you isn't being considerate or safe.

"55 in a 70 has everyone on your bumper including semi trucks. I'll do 62 and take the 8 mpg hit."

I have found that sticking to the far right lane I don't have anyone on my bumper. Most drivers have pulled into one of the left lanes before they get to me.
It's interesting to see how traffic moves in groups of cars, all trying to get around each other, in a minute or two they've all passed and the road is empty except for us slow moving vehicles.
After a rest area stop, or gas stop, you start to see the cars that passed you earlier, passing you again. 🙂

Took me 50 years of driving to realize speeding didn't get me there any faster.
Also even if you did 80, there would be someone on your bumper wanting to go faster.
