If it doesn't sell by this coming weekend, I plan to go look at or possibly buy a 1986 F250 regcab 4x4 with 4spd and the good ol' 6.9. The drive home will be interstate so I figure it's a good time to check my mileage out and see if something is unusual. I'm not sure of the gearing and I know that has alot to do with it but I would like to get an idea of what to look for. I plan on running around 65-70 all the way home ( if I don't get run over first, I75 in GA). thanks for the info and sorry if it's been asked before, I looked and couldn't find any info on mileage.
