I'm curious to see what I can get out of this with the manual trans but 4WD. My other '90 got 22-23 at 65 MPH with 5-800 lbs. in the bed, although it was a 2WD automatic with 3.21 gears and 215/75R15 tires. The worst it ever got was 19. The manual trans in this truck will help, but the 4WD, 3.55s, and slightly wider tires will probably negate most of that gain. Oh well; I have a Civic for the majority of my driving and this truck when I need it. Can't pull 2000 pounds of stuff plus the necessary trailer with the Civic.
Build Thread:
Current Mods: None yet.

Planned Mods: A tachometer sure would be nice, as would narrower tires and wheels with a smaller offset. I'll probably pull of the mud flaps later on.
