Wow! I guess a guy could do an entire competition on a single UDS! This is why I love this web site! SO MUCH KNOWLEDGE!!
So if you had to recommend the best way for us competition virgins, would you recommend a single smoker or multiple smokers? I would think multiple would give a little leeway so I wouldn't be opening/closing/opening/closing over and over and killing my temperatures.
Yeah, if everything goes right, you can do it on one. But if you have a stubborn butt or brisket you can have an issue.
See my recommendation above for a great way for a new team to start.
