Robbie, have you driven White Rim in your 80? If so, how did your fuel consumption compare? I tend to get the equivalent of about 10 MPG on average, although I prefer to do my calcs in gallons per hour. It's funny, though, my truck generally gets close to the same gal/hr regardless if it's 65MPH on the highway or intermittent 4wd-low.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
