For the record, what 'type' of smoker are we referring to? I see that PB has gas, electric, and pellet fed.
I toyed with the idea of converting my WSM to a pellet unit but had too many questions about it working properly. Particularly the exhaust. SmokeDaddy came out with a 22" version a few years ago, and I don't see where they're even available now. Too many issues?
All things being equal, the vertical versions offer up a lot more space. My little Traeger can do a whole rack of St Louis ribs or 2 racks of bb's. It's biggest drawback is yer not going to get a 15lb bird in there without spatchcocking. I digress....
Regardless of choice, I'd like to see some serious attention given to heat distribution. I'm sure it can do low and slow all day/night long. But what about the higher temp sensitive cooks like pizza, breads, deserts, etc. As is, I just set my temp and cook/bake.
I won't be joining in but will watch closely.
