I'd do it again...
Closing in on 1:00 and I have two butts on the Primo Jr. Not the XL, just the little Jr! I've also cooked a good sized full brisket without any concerns.
If you haven't picked up on it yet... Yes, I really enjoy the Primo. First, there are all the benefits of ceramic cooking. The extra space from the oval shape is a great bonus. Earlier this evening I grilled hamburgers. Tonight it's low and slow for butts. It can hold temp for 10 - 12 hours without a concern.
I use an extension on one side only occasionally but use the deflector racks constantly. I had a set of fire bricks already so didn't look at the D plates that are available now. Suspect they would be nicer as the bricks are a bit thick.
So, before I go all gushy on this thing. Any questions in particular?
