Someone please point me to a thread on how to get started.
A 10" or 12" camp DO is a good one to start with. Lodge is generally considered the best DO, but Camp Chef, Cabela's and other also make good pots. Cooking Outdoors is on YouTube and has lots of videos that might be helpful. https://www.youtube.com/user/CookingOutdoors/videos
Lodge also has videos, recipes and other info on their website. http://www.lodgemfg.com/recipes/outdoorentrees
The vitamin stores should have the flax seed oil, also Amazon.
You got a good oven! I use my 8" more than any other, next would be my 10". It all depends upon how much you are cooking. Google is your best friend to find reviews and best prices.
Always check the pots when purchasing or being delivered. The pots are heavy and might get tossed around, the packaging is not bounce proof.
