Berkshire MPG
Do have a great report on my Berkshire.... Went to Nashville and back these past two weeks and I got 11.8mpg to 12.5mpg.... Love that Mercedes diesel.... Speed "sweet spot" was 58 - 62 mph....

Also, mine was calculated by how much I actually put in and odometer reading. I think the computer was reading a little higher, like 10ish.

I also double checked mine - gal of fuel/miles driven. Was only 2/10 mpg off.... So computer is within an acceptable range as far as I'm concerned....

I've been amazed with the Berkshire. I averaged 61mph and towing my Honda Crv between Houston and San Antonio got 10mpg. Friends with older units(not Berkshires) are getting 6.5mpg. I have the 350 in my 2010.

I average about 10mpg and always check it by hand. I have seen that the mpg on the information center is usually higher than actual.

I also pull a CRV, but with a 340 engine. I stay below 65 mph and recently got 11.4 mpg on trip from Upstate New York to Georgia. I'm told that if you have a DEF system, that was suppose to improve your mpg by at least 10%. That may be the reason that newer models are doing better than older models.

I haven't heard of any similar sized motorhomes that achieve this kind of fuel economy. I'm on motorhome number 3 and I feel that the Berkshire will be my best and last.

Does anyone publish average miles per gallon for motorhomes? I have never seen any data. Also, those Berks that I see for sale, don't highlight this very important attribute. If I didn't already have one, that would be the hook that would get me to buy.

Just completed a month long trip that totalled 5000 miles with an average of 10.5 mpg in my 2011 390RB-60. I am more than pleased.

The one thing that the web site doesn't mention is that the air we breathe (and put in our tires) is about 78% nitrogen.

So if your statement is true that means my body will be cooler when breathing air here in Arizona at 112 degrees F. and my body won't have a premature blowout?
