I've smoked lots of stuff, but for some reason, never a whole turkey. I have a 14 pounder that I am planning on smoking this weekend. Other then thawing it - what should I do with it?

I am planning on rubbing it just like I would a pork loin. Do you put anything in the body cavity? Should I brine it first? If yes - for how long? What about injecting it? I know a lot of people go that route, but I think that by perforating it with the needle would allow a lot of the juice to escape - and I hates me some dry turkey.

And how much time should I plan on letting it smoke? I use an el-cheapo brinkman charcoal smoker, and try to keep it in the "ideal" range on the thermometer.

Any advice would be greatly appreciated.
