I also think you'd be happier with a front loading version. Both my smoker's are front, and the racks are easy to rotate (the bottom racks get done quicker).
Here are the burners and you also have to order the orifice from the accessories.

I have to agree. Front loading is the way to go.

Had a Big Chief for several years and then upgraded to a Bradley....and I love it.
That makes sense. The bottom rack is closest to the heat. I see some smokers on the market that have a smoke-generator separate from the
meat box. I suppose that makes it possible to use a colder temperature. Does anyone use one of these smokers?
