No. The cabinet, or specifically, gravity feed smokers are not offsets. These are considered vertical smokers as the smoke enters from the bottom (side) and travels upwards through cooking chamber. An offset also has a firebox on the side, but smoke travels down the length of the bottom of the cooker before turning 180 degrees and being redirected through the cooking chamber. The tale/tale sign for an offset is generally that the firebox and exhaust are on the same side.
I love my insulated vertical cooker because I can hook up a fan/controller, set the cooking temp, and walk away to do other things during the cook. Offsets, at least mine, generally consume a lot of fuel and therefore I use wood that I feed about every hour. The gravity feed units or vertical are more efficient and I use charcoal. Perhaps a pic would help...
