Brining is your friend. If you go this route, put in the brine water whatever spices to plan to use on the bird when smoking it. Also, you don't need to go the low and slow method when smoking poultry. Basically, you are roasting it inside the smoker instead of the oven.
If you're a dark meat fan, remember that the leg quarters will come to temp faster than the breast meat. Put a digital thermometer in thigh and breast. When the thigh gets up to about 155, put foil on the whole leg quarter to slow down the cooking. Pull the bird when everything is 165 degrees.
