Barry, the Old Country smokers already have these covered. There is a good size baffle inside the cooking chamber that spreads the heat/smoke as it comes from the smoke box .The exhaust is right down at grill level so it keeps more smoke down on the meat. These are both points I would use when trying to steer a customer toward an Old Country, plus the very heavy gauge steel. That Old Country Pecos that Jack bought is probably the best smoker for the money out there.
Ken, you answered that one before I could...I am absolutely sold on this smoker like I am on my infrared grill. The things you mentioned are good. PLUS...the door to the firebox fits an inset and the HUGE steel dampers fit so well. The lid is inset and heavy so that it seals shut. Don't get me wrong - this smoker is not air-tight, but I didn't see smoker coming out around any seams or cracks. The fire-box is oversized almost and holds plenty of wood for a sustained fire regardless of the temps.
Again...you guys hafta realize I am just a "backyard jack" when it comes to cookin'. I'm still at the elementary level. I'm in it for the fun and "sport"...the "Challenge", if you will. Like golf, their are a lot of clubs to choose from, depending your lie, distance to the green, etc. And even though you may play poorly today, the next round may be your BEST round. And even with your best round, there is always the thought, "if I had used my 3 wood on no. 6, I could have hit the fairway." Anyway, that's where I am and I am having so much fun.
I am lookin' forward to the summertime in the backyard. If you're ever down this way, gimme a call and I'll try to cook something for you.
