I always like to make a whole smoked turkey...
Brine in water + apple cider + salt + brown sugar...
smoke over green apple wood chunks (or seasoned apple wood soaked in water for 24 hours)...
and Cider + water in the liquid tray... usually takes 8-12 hours to smoke, depending on the turkey size...

I usually get green apple wood this time of year from local apple farms, as they have usually just pruned their trees for the upcoming season...
and they usually have big piles of it around...
