Anyone here got links to good info on the history of development on these trucks?
Particularly the evolution of the M939.
For example, I've read that the M939 was a Product Improvement Package upgrade from the M809.
Were initial M939s new production or the result of RESET mods to existing M809s (like is done with aircraft)?
Any history as for the whys behind the changes between the M809 and M939?
