All good advice there, fellas. And, as Pineywoods mentioned, size will matter eventually...the smaller verticals can handle pork butts, chuckies, a couple chickens or medium turkey just fine. When you want to do full slabs of spare ribs or a brisket...call houston, 'cause you'll have a problem.
I have a nearly 6 year old GOSM, recenly converted to charcoal for smoking sausage loafs, canadian bacon and such...good little rig as a gasser, just wanted a smaller charcoal rig.
The Smoke Vault 24 is very nice, was a gift for father's day from my kid's this year...love that one too...they are somewhat spendy.
Good luck...hope to see your smoker's offerings soon!
