Mossy Mo and Tatonka have one - and Hornzbee has a Yoder too...
I like to season a new pit with peanut oil. There will be instructions from Yoder on the "break-in" or seasoning process. You will find there are 3 basic ways to use the pit - with many variations.
1. With the drip pan in place ( some foil it - some do not )
2. Without the heat shield/drip pan in place
3. No drip pan, and the Grill Grates for a great sear. The Yoder wil sear without the Grill Grates, but it will sear fast with them. Nice tool to have.
Get some in-oven thermometers and play with the sliding baffle and check temps thru-out the pit at different temperature settings on your control panel. Now you will get sense of where the pit will cooke hotter or cooler.
A lot of folks like to get a couple pounds of bacon, and space the slices out evenly - to watch how the pit cooks, to accomplisht he same thing as the thermometers will do. Plus...you have some great bacon to eat when you are finished!
