    I was at the dealership last weekend, and the sales guy was telling me that the E450 rig he was pushing me towards got "about 12-13 mpg, just like my F350 with the same V10". I didn't bother telling him that we had an F450 flatbed at the shop "with that same V10" that averages 8mpg with mixed driving (often heavily loaded).
    The same guy was telling me that the diesel Transit and Sprinter based RVs get 14-16, which doesn't seem too unrealistic.
    What have You got, and what's your real world experience?
    TIA

    I have no personal experience, but every V10 RV I've read about averages between 8 and 9mph. Cs, As, whatevers.

    8.257 MPG Imperial....yes, when it is that low, you go to 3 decimal places! 1992 Homebuilt RV on an F Superduty chassis. 460 gas. Just under 33,000 KM's on it, so still as fresh as a daisy!

    Kinda surprised at bcbullet's example, and Hannda's mention of class A. My folks had a late '80s calss A with a 454 that never did better than 5 mpg, and often less.

    That is imperial....works out to 6.88 US MPG. And I BABY it...90-100 KM/H on the flat and one hell of a lot less uphill. Downhill is whatever gravity assist will allow while still keeping my foot out of it! :lol3
    Don't sweat the $$$, enjoy the experience! :beer

    Our old 1991 24' Class C with 350 Chevy got 9-11 mpg on our camping trips, never outta flatland Florida.

    Our 1996 25' Class A with 454 Chevy got 8-9 mpg on those same in-Florida trips.

    All at speeds of 60 mph or less.

    My 1997 Dodge Dakota w/3.9 liter V6 pulling a 21' travel trailer got 11-12 mpg around FL at same speeds.

    The salesman is exaggerating by 30%. Double digit mileage with a V-10 class C might happen at 45-50 mph. If you cruise at 60 you’ll get around 8.

    Our 5 cylinder Winnebago View regularly returned 15-16 mpg at 60 mph towing a landscape trailer with a motorcycle on it. The newer V-6 does 12 - 14 for most folks

    Our rig now - a ‘17 GMC 2500 6.0 gasser towing a 29’ Winnebago trailer is returning 8.2 - 8.4.

    In many places diesel is 25% more than gas. Then you have to buy DEF. While I admit my 2500 never sees a gas station it doesn’t like, the extra cost for a diesel platform plus the other extra expenses didn’t make sense for us. After nearly three years with the View we just plain wanted more room. Having a truck to run around in while camped is great as well. We almost never drove the View locally once we had it in camping mode.

    As I expected, lots of folks here are also on the Travel Trailers Because thread too. And yeah, I'm waffling back and forth between a smaller RV and a half ton towable. I like the idea of having my truck along for local travel, and the fact that it'll go a lot of places a 23 foot class C couldn't dream of. I'm definitely a boondocking kind of guy

    Most trailers aren’t set up for truly comfortable boon docking out of the box. Don’t forget to figure in a good generator and a second battery (or two 6v batteries) into your pricing. The class C will have a generator built in.

    Also remember it’s not just length - it’s width too. A 23’ sprinter or transit is narrower than the V10 platform, as well as many trailers. It makes a difference in how roomy the interior feels. Lastly, A 23’ trailer offers more living space than a 23’ drivable, but doesn’t offer the conveniences while traveling that the drivable does.

    The only regret we have about the change we made is that the build quality of the View was definitely better than the build quality of a Winnebago towable. Other than that the towable platform works well for us.

    We had a 2005 Corsair 24' on an E-450 chassis , It got 15-16 m.p.g. ( imperial gallon ) That was a 6.0 litre turbo diesel , unfortunately it blew the snap to connect fitting and many $$$$$$ later we got nervous and sold it . We now have a 23' Adventurer E-350 with the V-10 and It gets between 9-11 mpg . You could drive the diesel like you stole it. Pleasure to drive .Travelling in a class C is way more comfortable and relaxing than truck and camper or truck and travel trailer . You never have to exit the unit except to gas up , which is often enough cause you can't get a decent engine in anything common ( cummins 5.9 or 6.7 ) . The Sprinter chassis has got an 11,000 GVWR where the Ford 350-chassis is 12,500 and the E-450 is 14,500. The Sprinter motor is a jewel at only 50 ft lbs less than the V-10 at sea level . Probably double the fuel mileage . Find a layout you like and leave a little capacity for a bike hauler . The price of entry may be a lot of fuel to make up though.

    Our 2005 Sprinter RV with the 5 cyl turbo diesel gets 20mpg if you are easy on the gas; ie at or below 65. I don't really check it much anymore. When we pull a motorcycle trailer, it dropped to 15 or 16, course those were at freeway speeds, about 70. I've gotten used to driving slower than I used to, partly because it runs cooler at lower speeds, especially climbing long hills. Guess I just think it's a fairly small engine that will last better if I don't keep the turbo spooled up so high just to drive 75 and above, which it has definitely done in the past.

    I had a 31' class "C" with the V-10 (E450 chassis). When I bought it, the salesman said bet on 9 mpg, and he was right. Almost always averaged that except on a long downhill, with a good tailwind. Then 11 mpg until the flats. Didn't matter if it was loaded or not.

    Matter of opinion. While it takes more concentration to drive a combined 50’ of length compared to our previous 23’ View, the truck is so much quieter I find myself much less fatigued at the end of a day of driving. It was great being able to have the fridge accessible while driving, but now we just pack a small cooler of food and drinks. We can still pull over anywhere and use the bathroom in the trailer.

    Yea , I hear you on the quietness , but looking for parking spots when shopping ,fueling , camping , and we only pull over for the driver on bathroom breaks works better when time is important . We can pullover at nite and never have to exit the motorhome . If you have a set destination with lots of room and your going to be there a while we were more comfortable in our truck and toy hauler . The Class c is better for wandering around . Bike security is not as good though . The C works for us now , It may change again as needs change.

    This kinda addresses my dilemma in choosing a TT or RV. There are lots of places that you just wouldn't drive the 50' combined rig. I can think of a couple in national parks right off hand, where anything over about 22 feet is prohibited along with trailers. Going To The Sun Road, in Glacier NP, and the highway through Sequoia NP for example. The posted limits are 21 and 22 feet. You can get through with something bigger, but if you have a problem, you're 100% at fault. Plus, don't be that guy who needs to make a 16 point turn thru the hairpin curve!

    Funny, next week the family and I head to Alaska for two weeks (wedding) and have a rented RV waiting. We knew the fuel economy was going to be crap, but figured we would make up the cost by not needing hotels.

    I didn’t think it was going to be single digit crap, but...

    In the decade plus we've had our current MH (32' Class A w/454), I've never checked the mileage. Scared to. I did add another $150 to the tank yesterday - would have filed it up but I didn't alert Discover in advance and they cut me off.

    That was a concern of ours as well. But ultimately I figured I’d rather have more room rather than a 24’ RV that allows me to cramp :lol3 all kidding aside, we loved the View. I was ready for more room.

    By the way, I’ve ridden going to the sun road on a motorcycle. I’m not driving *any* RV on that road!
