My K10 is gunmetal, got an Outdoorsman sticker on the bed too.
Mr Neutron - where was your truck built?
Joshua Keith - I see that your truck was built in Oshawa.
If you are desperate to know more you have the luxury of two ways to find out:
You can send your VIN to the GM Heritage Center and they will send your the original invoice, which will include option content, pricing, any discounts, build timing and selling dealership. Last I knew this cost $50.
You could also send your VIN to GM of Canada. They return a similar range of information but also sometimes include additional tidbits like build quantities and commentary from George Zapora. I do not recall what the fee is for that service.
