6B is a 2ton [6400], as Fumblin sez, and that would be a Viking, not Apache - the smaller 6B is because it was added on after the plant and sequence number, when they decided what bigger chassis the cab was actually going on - if that VIN is on an
Apache it's not the tag that belongs to that truck, or the cab has been replaced - does that VIN come from the cab tag or the title paper? might be that someone scrounged up a title for a truck that didn't have one
is it a half ton?
