Hey Chevyman,
Welcome, and this is my soft spot as you can tell by my bolt name. Post us some pictures so we can see your new baby. I just got number 4 home (in less than 2.5 mos I might add) and judging by the strength in my wifes hands and the pressure around my neck, I think I have to quit for awhile.
Of course they would be, the guys are right about the info. I couldn't get the decoder to work for me, but I just went thru the pains of figuring all this out in CA....fun. You will not find a serial number stamped on any plate on your truck. The vin will tell you when it was made, what size it is, and what number it was from the factory.
Your truck isn't red with little circles on the doors is it?
