Just a guess, because I'm not familiar with any of them, but maybe they can't pass the FMVSS or CMVSS checks, or emissions standards, and so aren't available in North America. Unsafe at any mpg...... (sorry, Ralph Nader joke)

Default Post your MPG

Ram Promaster 2500 V-6 gasser, maiden voyage from Phoenix AZ to Stephenville TX via I-10 and I-20 roundtrip. 2218.2 miles 140.3 gallons of gas averaged 15.8 MPG. This was driving 70 and 75 mph and fighting strong side winds both ways on I-20. Plan to slow down on future trips and travel the blue highways.

FWIW, not a class B van. Winnebago N24V low profile, with some variable (~10-25 mph) cross winds, and varying but minor grades, loaded weight around 10,400 lbs. Under 3,000 miles on drive train.
At a cruising speed of 100 kph (~62 mph) we average 15.7 mpg.
Drop to 55 mph and mileage increases to over 16.5 mpg.
Speed up to 65 mph and mileage drops to around 15 mpg or slightly lower.
In residential and on back roads, at speeds of 50 mph and lower, the fuel economy increases even further to over 17 mpg and up.
I'm amazed at the predictability of fuel consumption numbers and the affect of such seemingly minor increases and decreases in mph, on the MB 3.0L V6 diesel engine. If I baby it, the mileage goes up accordingly. Go the other way the decrease in mpg is proportional, it seems.

Drove 10,500 miles across the USA and back.....our average MPG was just over 18 MPG... that's 19 to 20 flat ground and 16.5 to 17 climbing mountains... Just call it 18.. going 60 to 65 MPH. ...

The Mercedes Benz Sprinter diesel is a very efficient engine...

If you figure 18 MPG..it's a conservative estimate...If you are stuck in a lot of stop and go traffic ...it will be lower...

People like to exaggerate MPG..this is not an exaggeration.....

In what I would call almost ideal conditions and at a cruising speed of around or a little over 100 kph (~62-64 mph) we averaged 17.9 mpg, just a few days ago. Mostly flat terrain, almost no wind or traffic related turbulence from any direction, fairly smooth asphalt pavement road surface. The difference was tire inflation pressure. I firmed up the tires to 70 psi front and just below 80 psi rear, cold inflation temperatures, at our expected loaded for travel weight.
The other speed related relative mpg differences were consistent and proportional at those tire pressures.
Can't complain about that.

There are plenty of Class A's and even some thirsty Class C's getting 5 to 7 MPG...the fact that the Class B's as a whole get 15 to 22 depending upon the engine you have and the road and speed conditions is amazing.......

A lot of Class A's like to say how much they like their space, but, when I get to the campsite or destination where I'm going... I have the same outside space they do.... plenty of it....

And, if I want more inside space...I have that at home....

Different strokes and all that.

On TDY near Greenville CA. Next stop Tahoe area.

I think my Paseo is finally getting broken in, the gas mileage is starting to climb a bit. On our last trip, we averaged 12.8 towing this 5x8 enclosed trailer with two motorcycles inside (total trailer weight about 2000 lbs) plus a full load of water and propane in the van. This was mostly keeping the cruise control set on 65-69 mph which seems to be the sweet spot for the van. Any faster and the mileage takes a big hit.
