You first season it with smoke by putting 4 oz wood in the woodbox and running on 225 for a few hours. Next, season it by cooking a nice size butt or shoulder. I use Pam for grilling on the grills/racks. Don't forget to cover the bottom with HD foil and punch a drip hole. Also, cover the woodbox with HD foil. When finished, put the grills and racks in the dishwasher or soak then scrub them with dawn. Wipe out the interior with paper towels, no cleaner. Clean the outside with 409 or Fantastic or similar. For cooking the butt or shoulder, use the advice you have been studying on this forum. Remember to take explicit notes to include meat temp, outside temp, wind, type and amount of wood, cook temp, weight of meat, time, etc. Use a digital probe in the meat and do not open the door until it reaches the target temp.
