1 Us gal = 3.8 L versus
1 Imperial (Canadian) gallon is around 4.5 L. = More gas per gallon.
I can get around 20 mpCg on a flat road, on cruise, at around 100 kph (62.5 mph), with no wind or hills.
Could be-- although the PO had the van in Arizona for awhile. But it would be a way of "inflating " the mpg without telling a fib. So, you're saying a US gallon is 84% of a Canadian gallon? And if Canadians ( love ya) use liters, then why are there even "gallons"? Why not "4 Liter" increments instead of ---- 4.5?
When I drove it home, totally empty except gas and 1/2 tank of fresh water, from AZ to MT, I drove Hwy 93, through flats and mountains in Idaho and Montana - I was sorta afraid of it , so kept it at about 65ish, and I got 16+. So, I don't know about ever getting much better, with it now loaded for travel, and I tend to run it closer to 70 now. Although with gas at $4., I may be slowing down.......

Yes, about 84%.
Because like you, we are descended from Brits, and have to deal with a thing called an Imperial gallon,
which is 4.5 litres, and still exists. If we were all measuring fluid volume in litres, there'd be no issues
about converting. We'd all use miles per litre. ( btw, 16mpUSg = 4.2 mpl = $0.21/mile, at a gas price of $3.50/USgal )
So, now it's my turn. Why is an American gallon smaller than a Brit gallon (3.8 versus 4.5 litres)?
Most Canadians are at the least paper trained, we rarely fib, and we make excellent pets.

My Class C gets 8 mpg and that does not encourage me to drive it. We went larger for comfort but are less likely to use it. We are more "frequent trips of less duration" people than I thought when we bought the "drive and stay month Class C".

Anyone want to to buy my C?
Hi, Steve here, the newbie with 1994 Ford Coachmen w 351 Ford engine. Checking in after my first road trip from Carpinteria to Lone Pine to highway 120, through Yosemite, to Watsonville and return. Around town, idling and running generator; mileage as low as 10 MPG. On the highway, 15+. Even got 15+ on the stretch over the Tioga Pass. Extremely pleased with the MPG, mostly driving 60-65 MPH. Learned the cruise control makes RV go up or down 1 MPH per tap on control. Discovered that I took too much stuff. RV is like a woman's purse (pardon the sexist remark): put too much in and you can't find anything. The fold out bed in the middle of van, not too handy, but I can easily adapt and live with it. Also learned to move at half speed or less inside the van to avoid banging head and other body parts into things. Think before you move is a good plan. The RV battery is not being charged by the motor. I have to fix that. The generator "lopes" after it warms up. Also have to fix that. Everything else works fine, though I haven't tested the space heater or the toilet. The shower/bath is for midgets, but it can be done and is way better than nothing. Overall, I am very pleased with the unit. The Ford drives nice and is economical. For 10.5K, a very good deal. You can't have compactness, driveability and economy without some trade off. Dog and I had a great time Hoping to go to Bend, Oregon for cycling nationals end of August.

Many years ago I added water induction on my car. I'll say it did add at least 2 mpg. I haven't tried it since computer control though. As for how I did it I attached a T in the vaccum line that pulls vaccume from all cylinders. The one I used was at the base of the carberator. Attached to the T I added a hose that I installed an aquarium valve. On another leg I put the hose into a gallon jug of water. I would adjust the aquarium valve to draw how much water I wanted it to pull and also to suck additional air in another valve. With both those valves I achieved the 2mpg consistant to at times I did get more than 5 mpg compared to mt benchmark of prior to adding it. There may be other factors but I believe I can without any doubt say I improed it 2 mpg

New to this site-we're in the thinking stage of getting a used B. Which class B gets the best mileage highway and in town? I am leaning toward the Sprinter b/c the diesels get better mileage ( so I've read). I like the style of the Sprinters but have not seen the inside of one in person, or any B for that matter. This week-end we're going to St Louis to an RV van dealer that seems to have lots of new and used models. So we have lots of questions but the first is about MPG.
Thanks!

I think the diesel gets better fuel economy. Maybe even enough to overcome the higher price of diesel fuel.

The Sprinter-based Class-B can be built with single or dual rear wheels. They are typically taller and wider inside, with more storage space.

There are a few folks on this forum that have these, and have good photos of their interiors. Do a search for "Sprinter", to find them.

I agree, except that many (most?) of the Sprinters don't have a lot of storage space for their size, at least when compared to Roadtrek Chevy based units. They have very open floor plans, and large bathrooms, which leave less space for stuff. The 190 Roadtreks, with temp bathrooms use the space the best in our opinion, but they are not wide open like many of the other brands. A big advantage for the dually versions is the elimination of carrying a spare, if you so choose.

By "wider inside" do you mean more open floor plan?
I though they were taller but narrower overall.
The ones I saw at the London RV show had all the Roadtrek models including the new one on the
Nissan truck chassis. The dealer was from the London area, but I can't recall the name. Said there were only about 10 of them in the province. I didn't ask about mileage, sorry.

Some of the storage is more useful than the other. Our C190V would make better use of the storage space, if the power couch/bed were simplified, and non-motorized. Booster did a great modification to his bed, and opened up the area under the bed. The outside storage compartment would be easier to use, if the door-opening were larger.

From Roadtrek: Storage capacity

Chevy 190: 62 cu. ft., 80 w/options

Chevy 210: 74 cu. ft., 81 w/options

Sprinter RS: 55 cu. ft., 81 w/options

I assume the "options" are the cabinets that replace the extra seats.

I have the older outside storage configuration with swing up hinged doors. Those newer ones may not
be more convenient, but the slide out style drawer looks better than mine. Not sure what else could be done, the vans aren't meant to be full of beds, galleys, and bathrooms, they were supposed to be full of cargo.
Except switch to a travel trailer. Just imagine the wide open (storage) spaces.......
