I don’t really know but I can put one 15 lb turkey on my Daniel Boon (458 square inches) and it cooks even. With 1000 square inches you have I would guess 2 turkeys. Maybe three medium size but it probably would cook the best with 2. Just my opinion. Hope it helps.
Based on the size of mine I was gonna say 4 but Thomas beat me to it. They have a large second shelf available, which came with the package I bought, and you could easily get 2 more on that. Great chart though!!
I had been saving for a Yoder YS640s but my 3 year old decided to throw a nerf gun at my 65 inch Samsung that was less than 2 years old. After buying a new tv and a stand, I've got just enough left for a rec tec. I'm trying to force myself to want one. Not having much luck, I love the size but the 2 big issues I'm having with it is 1. its not made in America, and 2. no way to direct grill over flame. These are two things you can get with a Yoder, but boy do they make you pay a premium for it.
