Incidentally, seems Bobio's greatest mpg secret was drafting behind semis... anyone else try that?

Draft behind a semi!!! Craziest thing I ever heard of. I'd NEVER risk the lives of the passengers in my RV much less my own life drafting a semi !! Completely Crazy!!

Driving too close makes me nervous and I don't like driving nervous.
Me too I can't stand being nervous and I have to see what's in front of me. I also ride a Harley here in Colorado and have seen the rocks and other stuff that come from trucks.

All this talk and has anyone explained how they calculated their MPGs?
Correct way (IMO) is fill tank, drive and record miles, fill tank again , divide miles driven by gallons used. Even different gas pumps can shut off at different points of fill.
Onboard computers are suspect.
btw I have scored 9.5 mpgs best and 7.0 worst in my 460 ford 34' class a .
But you can't defy the laws of Physics ,Captain!

Exactly!!
Down a 6% grade I see 256 mpg on my VMSpc, but then in the Columbia Gorge into a heavy headwind @ 70 mph I also saw 3 mpg. Up a hill I'll see something over 2 mpg too.
On the flats, no wind and holding 62 or so I see 16 mpg, if I slow down to 55 it goes down to 12 to 14.

And you have to do it over thousands of miles too, not just one trip or one fill up.
To have a believable readout from the Cummins onboard system takes 144,000 miles according to their white papers.

I don't even think about it....................Just keep fillin' it.
A lot of people ask "What's it get for mileage?"
I say "If I got to worry about that I shouldn't have it"
...........And that's the truth.

That be same here. Just fill up somewhere when tank gets under 1/2 I've checked mine a couple of times. For what reason??? I had a destination and was going there no matter on fuel milage.

The easiest way I can imagine is using the GAS CUBBY app. They have recently been acquired by FUELLY so there is also a web version.

Fuelly & GasCubby Unite

The app is still available on Itunes both with a cloud and non-cloud version.

We have seatbelts for 10 in our motorhome... and we've used all of them at once on more than one occassion. With 10 of us in there, at 11mpg we get better mpg/person than a single person in a prius. If you look at it the way I do, It's like we're getting 110mpg!!

-cheers
