Just as a followup, this has worked very well for me and is highly recommended. Its apparently made by Brinkman, since a call to the listed Kenmore customer service line took me to Brinkmans customer support.
I've really appreciated being able to add/access food, water and chips on the fly very quickly and without having to remove the lid and then the top rack(s). With the four separate racks, I can load up each with food and then at the right time stick it in the smoker in 3 seconds, minimizing heat loss.
I also noticed that the arrangement allows for rib hooks or hanging fish racks to be hung from the top rack with excellent access. I could do four full racks of spare ribs or four whole fish in this with no problems. A little homemade heavy aluminum baby "coat hanger" hook inserted in a turkey would also let me get away with about an 18 pounder.
So now I know whats for thanksgiving.
On the last session I did baby back ribs, a chub of Jimmy Dean sausage with a rub on it, and another batch of ABT's. I put a LOT more spice rub into the cream cheese, mixed some minced little smokies in, and upped the green onions. I removed the pepper seeds but left most of the membrane in there, and used a thinner bacon that would crisp up more quickly. Perfect. A little spicier, more flavor, and overall an excellent artery clogger.
I glazed the ribs and the sausage "fatty" with hot jalapeno jelly...which generally isnt super spicy but has a nice mix of sweet and hot. I added a little cayenne and honey to the ribs glaze and straight jelly on the fatty.
I think the next time I'm going to do a chicken and set one of the jimmy dean sage chubs over it for some auto-basting...
