Cool pics, Jack!
That appears to be a huge water separator on the truck. I noticed that my Erie has a heck of a water separator, too. I guess it makes sense - you wouldn't want to have that water-in-the-gas problem at 5000 feet...
I'd definitely like a copy of the Wayne 100 if you find it, Dodo.
The Bowser 276 I am anxious to see.
Thanks,
Wes
