Did a 2300 mile trip in my 1999 Class C V10 Four Winds last summer and averaged 13 mpg. The trip was in Oregon were speed limits are low, and even if they were not, the roads keep you at 55. Had all the power I needed even in the Blue Mountains.

I think you need a new calculator.

Did a gate to gate test on I-95 at60mph, 9mpg , 14k load, no toad other wise super slab+ stop go off interstae 8.1 to 7.2 can't beleve anybody gets 11 in a "c", also make sure we all talking same size & abt same weight not a 22 on a 350

I've averaged 7.7 MPG for over 50,000 miles. That's driving conservatively - - 57/58 MPH on the hwy. (That's with pulling a toad about 99% of the time.)

But I have a large front bunk (great headroom inside) that pushes a lot of air - - think that the biggest contributor to my poor MPG.

Had a 26' class C with the Ford 460 CID V-8 back in the '90s that got an even 8 MPG.

A Ford V-10 mpg is approximately 6 miles or less in stop and go traffic "city driving" and 8 to 10 mpg on highway driving at a conservative driving speed, the higher the speed the more consumption of fuel, I calculate 6 mpg
City and 9 mpg highway, taking into account that mountain driving and pulling a toad will be less mpg, with that in mind we calculate the average fuel for the trip.

Other engines in other vehicles will get better mileage and some will get less, there is not much that can be changed, unless you want to build an aerodynamically wind slippery RV that gets what you are looking for in mpg.

I have a motorhome b/c I used to have a truck / trailer combo. All the negatives you cite above about riding in a motorhome seem like nothing if your towing a long heavy box behind you.

Driving my motorhome is a treat compared to that.

When we started motorhoming we were a young couple with kids paying the mortgage and living from small paycheck to paycheck, cost of fuel was more of a limiting factor. Cost of fuel is a bigger issue if your style of motorhoming involves lots of driving and touring vs camping. IMHO, the harsh ride on typical concrete highways, road noise, and overall stress of driving a motorhome for long stretches, often in mountainous areas, does not compare well to touring in most cars. We have done the cross country tours and camping closer to home in various sizes and types of campers and motorhomes over 40+ years.

I like the Ford looks but that about it. mph is not good. That why I wanted my Dodge Scotty with a Cummins diesel back. 14 towing the car trailer and 16 empty holding the speed 60 a hour. If I run 65 or higher the fuel mileage drops down. My buddy has a older Ford with a 360 engine and you can't stay behind him your eyes will burn from the gas fumes. I mean that. No way I am staying behind Jim. Class C Motor Homes on a Dodge with a Cummins would sell like hot cakes I would think.

^^^ Well said. Unless someone has very special needs, like to be sure everything's just the same every night, special food needs, travel with pets, etc. etc. then an RV isn't very good "transportation." To just "get somewhere" we drive and motel, or fly. As the cost of moving the "weekend cottage" from one nice place to another, priceless.

Unlike our motorcycles where the ride is usually the adventure, our RV's destination is usually the adventure. Some trips we just hotel it. All depends on what we're doing.
