Mine won't qualify, I do one big cook for the week then microwave the pre-cooked meals...
I know it's far from the oldest here, but my EZ code 3 wheeler has got if I have the date codes right, 2 Decades on her now. New to me, but was in the previous owners regular rotation, and is in mine now.
The JJP on the right is new out of the box this year so I won't call it old, but the 2 put together are my regular cookers. Like I said, one big cook a week. 2 if I am doing something special. Which reminds me, thaw the brisket...
