Tony and others,Jim, I can't speak for Richard, but I would say that things aren't so cut and dried that you can specify exact dates for many of the things you want to know. Introduction date of a particular truck, sure; but widespread adoption date, a bit more fuzzy. Likewise, a date when a ban went into effect is exact, but of course usage declined before that; and some truck designs simply became obsolete or superseded by better ones over a period of time. IMO you will just have to understand that "fuzziness" is part of the history.
