I think we have a Vin decode for the second gens in the tech section. As for SPX that would be pennymans department. He is like a walking Wiki on these trucks. Some day he needs to just sit down and do a data dump into our Wiki. While you are on-line surfing the net we have a radio station you can listen to. Just look at the top of the page for MMD5 Radio. You can request songs and upload to it. It's all member supported. I'm working on getting us a member map. Ya never know some day we might have even start clubs across the country. Only time will tell. This place is slowing becoming a Facebook for mechanics of trucks.
I told ya we get a lot of activity. Some days you can't keep up with it.
