Last I heard, Charlie sold the business. I've met him in the past at a dodge show, and to me he was a car salesman period. All hype, but absolutely no material at all to back up his claims.
Everything he quoted was from some obscure college in Wisbo, south Dakota, and only on Tug boats and earth movers, but never on a CTD or the like.
I think he is counting his money somewhere on a south pacific island...
