2014 Thor Palazzo with 6.7 Cummins and 2100 Allison Transmission. We get 10.2 pulling a Jeep Wrangler unlimited and 11 mpg not putting the Jeep. Our unit is for sale if anyone is interested.

MPG not a factor in purchasing a diesel pusher
 
My opinion! If mileage is one of your criteria in choosing which diesel pusher to buy, you are not going to be happy with any choice you make, thinking that maybe another selection would be better. Diesel pushers get 6-10 mpg, and the difference in fuel costs between high and low are negligible compared to other costs. The critical factors are (my opinion!): 1. Initial cost & affordability, 2. Reliability 3. Maintenance costs 4. Service availability 5. Comfort, room,and fit for you and your traveling crowd. 6, 7, 8, etc; your choice. Guardrail53 gave you good advice and the details. Listen to him, I would.

42 k lbs loaded with toad 550 hp 1875 torque cat 3406e 7.5-7.9 mpg at 63 mph . but I bought the coach for the power to use cruise on most hills and not have to down shift . that is way more important then any mileage . my last coach was a dog on the hills .

get the biggest engine you can afford and enjoy the ride

Caveat: Unofficially via my Scan Gauge, which resets between shut downs, and primarily driving along the Eastern Seaboard with little mountain terrain:
60,000 miles via
2012 Tiffin Phaeton 380 Cummins on Freightliner towing Honda CRV @ 65 mph
Average 9.7 (seems higher than others - I will recalculate total trip distances now)

2004 Newmar Kountry Star, 3136 CAT 330 HP, 3000 series Allison 6 spd. Varies from 6.9 - 9.8 MPG depending upon speed, wind, terrain, and generator use. Sweet spot is 58 MPH no wind, no generator, mild terrain for 9.8 MPG. No toad.

FWIW, both my 2011 Phaeton and our 2013 Bus gauges read 20% plus higher than actual hand calculated.

05 Country Coach Cat C9 towing a GMC Terrain. 63 MPH 6 - 7MPG depending on terrain, as previous member said fuel mileage is what it is. , maintenance is where a lot of the $ comes into play. That being said, I certainly like my DP so much more then my previous gasser.

2008 Tiffin Phaeton 36', pulling 2014 Honda CRV. 8 - 9 mpg, Cummins 360 HP, often adding Stanadyne Performance fuel supplement. I cruise at 55-62 mph regularly.

Not exactly in your search parameters, but my experience:

My first DP, a 2003 Itasca Horizon, 32T (yes, 32 foot a shorty) with Cummins 300, over 3 years, averaged about 9.8 mpg. One tankful, under ideal conditions, we hit 11.5 mpg.

Our current DP, a 2010 40' Winne Journey 39n Express, Cummins 340, towing a Jeep Wrangler, on an around the country trip of 14000 miles, averaged 9.3 mpg. We usually drive between 58-64 mph. (no DEF in this model)

But up hills, or with lots of headwinds, the mpg drops considerably, but all part of the lifestyle. And another note, we do see noticeable improvement in power and mpg, with no or only B5 the lowest bio-diesel added.
