I seem to remember that before I bought my Hydro-Dynamix franchise that the company literature stated that they were the founder member of the National Truckmount Association. I have never heard anything about it since and I don't know if I even still have the literature.
There again I could be mistaken, but I'm certain that they stated they were the founder member of some truck mount association. Where have you picked up on this from?
Cheers
