That is my drying rack and kitchen table. If you make one make it just wide enough so you can put your smoker shelves on top and on the lower cross members. That way you can dry things and carry them from the rack to the smoker. Your sausage dowels will fit as well.
Nice job on the drawing!
Here's the drying rack I drew up. Use as is or alter the dimensions to suit your needs. I made mine out of scrap oak boards I had but you can use whatever lumber you want to. Ask any questions you want, I didn't dimension the heck out of the drawing but there should be enough there to build it.
