Great to have you on board Terry!! Looks like you do some good work on the scale as well as the 1:1 scale stuff.
Love the Dually!! I'm a big fan of these trucks myself and have a 94 C1500 with 445,000 miles on her (the truck body & chassis anyways). These old trucks are just the "cat's meow".
Yours looks to be a 96-00 and is in GREAT shape!! Love the rat motor in there too.
