Sprinter 2500 4 cylinder/7-speed highroof. My daily commute in a mix of freeway and heavy stop-and-go traffic seems to be a sweet spot for mileage as I seem to get peak mileage here. It's 15 miles one-way in the morning and 19-miles going home (different routes due to traffic) and I always get between 28 and 29 MPG.
I have never gotten higher than that so those are ideal conditions. Lowest mileage I have ever seen was 22 MPG, and that's what you can expect to get driving at 75MPH due to the wind resistance at higher speeds. (I also have solar and roof vents on the roof.) Average is 24-26 MPG in mixed city/highway.

Sprinter Van Winne, 11,500 lbs and 4x4...getting between 14 and 17...
My last three fill ups in in Minnesota that I guess is B-10 biodiesel I had 18.25 mpg. I don't follow the readout on the dash but calculate it by gallons divided by miles. The dash readout is a variable to how you drive like coming out of a mountain will give you fantastic readouts.That dash readout overall is going to be at least a half gallon average low. If the final reading on the dash is about 17.7 mpg it will calculate out at around 18.2. More accurately I would take all fill ups add them together for a trip and divide by miles driven. That accounts for every driving condition encountered. I've had a consistent summer of Minnesota biodiesel and wanted to know if it was a hit on mpg.

I just returned from a 4,966 mile round trip on Winnebago Outdoor Caravan to Canada and kept gas reports for the whole trip.* My average mileage was 13.64 mpg and driving between 55-65 mph, wind behind me and in front of me at about 20mph during the trip.* I was also using the tow mode towing my Smart Car.* Gas price was a low of 1.999/gallon to a high of $4.165/gallon (in Canada).

This is a totally newbie question. The European turbo-diesel vans (Citroen Relay/Boxer, some Mercedes, Peugeot)-get 45MPG+Why doesn't everyone drive these???????

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)

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.

We have a 2012 RS Adventurous...3 litre V6 dual wheels, 23 feet
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.

Be thankful it's not 5 MPG like many Class A's
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....

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.
