By this, I mean little quirks or oddities about your truck for any reason...things only you really know that also come in handy for driving it...mine has the following:
*The only gear lined up on the shifter is Park
*The reverse lights only work if you hold the shifter up against the upper limit when it's in reverse
*Lockup in 4th requires flipping the toggle switch underneath the dash
*A full tank only registers as 7/8 on the gauge
*The fuse for the instrument lights has no glass
*The high-speed fan setting is disabled
*There's no cover for the dome light
*The choke is wired open
My guess is, though, my list is pretty small compared to what some of you guys can come up with, heh.
