[BFix] Thinking outload gas mileage and EB....

[Dan Davis]

I think you're right, because I drive a Heep Grand Cherokee as my D/D, and
it gets about 17 or 18 MPG.  But just like Jim, I have a company gas card so
fuel cost isn't really at the top of my concerns list.  That is until I hook
up the Bronco behind my 26.5 ft motorhome and fire up the old 460 gas
guzzling beast.  At 8 MPG it goes quickly.  Don't pass any gas stations or
you'll be sorry.
