Your UDS has only one rack? Most have two. You can do it on a gasser, can you get your gasser to hold the proper temperature? Some gassers do not like to run too low. Also, you will need some foil bombs, foil packets filled with wood chips and poked with holes to add smoke. Or you could put a chunk of wood onto your heat bars, this is a bad idea for the long term as it will cause the bars to be damaged.
