Well i seasoned it today. It does awesome on keeping temp. Got it up to 250 in about 30-40 minutes, threw on a split about every hr or so. Split being a piece about 4"x8". Maintained 250 all day and never touched the inlet damper and never needed a stack damper. Had a temp diference of anywhere from 3-5 degrees the whole time. Im thoroughly impressed with it. Anyways, while all that was going on i got the storage box skinned and on the trailer.
