I'm REALLY trying to save on MPG, and I know it's kind of an oxymoron in a way to think of an RV & MPG....
But I DO know that there are some class c RVs were built on 4 cylinder Toyota trucks. I imagine these to get much better gas mileage than even the 6 cylinder models.
So basically, I have 2 questions.
1) Are there any other types of Class C RVs built on 4 cylinder vehicles?
2) By chance does anybody know what kind of gas mileage a 4 cylinder class c is capable of?
Thanks a lot.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
I see some of the old Toyota C-Class MHs now and again still on the road. Not sure of the mpg or the size of engines. Sometimes a V-6 or even a V-8 may get better mpg than a 4 cylinder if the engine is having to really work due to size and weight of the vehicle.
Some other ways of perhaps getting better mpg in an RV:
B-Class MHs such as RoadTrek. No need for a toad with one of them. But must break camp to go places in them.
Our daughter & her husband rented an ">A-liner hardsided pop up trailer to travel to Yellowstone this summer; worked very well for them. They would always have it up and ready before we could get our set up. It didn't have to be level as well, no frig. A very simular hardsided pop up is the Chalet: A-liners and Chalets
For longevity, one can not do better than a molded fiberglass unit, such as Scamp and Casita.

Oh, Yes. we put 2503.9 miles according to the trip odometer and seems the Ford F-150 averaged about 17 MPG going up to Yellowstone and back this summer.

My folks pull a Chalet hard side pop up (like an A-Liner) behind a Toyota Sienna and do fine. It's the two of them , stuff, and the dog. They won't set any speed records but it's economical and fits in the garage. As far as the fuel mileage thing goes you need to figure how much your fuel bill is going to be. Generally it is chump change compared to the cost of the RV based on the amount of miles driven. A little math will prove the point.
They had some Izusu powered 3.9L Turbodiesels for a couple of years.
Sort of underpowered, for the size of the motorhome. Came in 28' long, front diesel, about 140 HP, only 90" wide so it was a bit tiny, but HUGE compared to the Toyota campers.
I have a friend that tows a A-Liner (link above) with a Dodge and a small V8. He gets decent gas mileage.
But don't be to concerned about the fuel mileage. The most expensive thing for me, when full timing, and driving 5,000 miles one summer with gas hovering at $4 per gallon was insurance. I only used about 1,000 gallons of gasoline to power my car and the minivan I was towing.
If I had "Gone Small" and only taken the van, I would have needed to pay for about 200 nights in a hotel room, or needed to spend several nights each month in a campground with a smaller RV (and smaller fresh water, black water tanks that need to be filled and emptied more frequently).
With my 30' motorhome, I get about 7 MPG. I can dry camp for about 2 weeks with the 100 gallon fresh water tank, longer if I bring home water while out sightseeing. Then spend one night in a campground, and 2 more weeks someplace that is free.
Grand Canyon National Forest is a favorite of mine. Lots of trees, some open meadows, ect.
So I might only spend $25 on a campground twice a month. And I can cut back on the insurance if I call them and suspend the coverage while I am parked someplace for the 2 weeks, just remember to get it back in force before driving again.
Don't know what milage the old Toyots's got but I have heard that they were really underpowered and if you saw a hill.....
I do not know of any current domestic motorhome that uses a 4 cylinder. I know if you go to Europe or Down Under that you can get them, don't know much about the milage they get but again if you need to go through hilly country you would be better off with a v8 or more. My MH has a 454 and going through the mountains it works pretty good, only a couple really steep grades where my speed drops under 50 mph. Can't image taking something like a small c with a 4 banger but each to their own.
I think it is only fair to others on the road to do at least the speed limit especially through the mountains where a good part of the drive is single lane each way.
FWIW, what we call class C now used to be called mini motorhomes and those built on Toyotas used to be called micro minis. Reportedly the 4 cylinder micros used to get about 15 mpg but you could not be in a hurry if you were going uphill.

I've seen a lot of old Tiogas built on a Toyota chasis and from the speed they are driving I ASSUME they're 4 cylinder engines. We regularly see several of them on the breach in south Texas but you rarely see them in the mountains. I'm sure there were other brands using the same configurations.
