This is where your smoking experience is going to pay off. Your turkey is going to cook slower at high elevations. Weather will play a big role in the cooking time. The type of smoker you are using will also change times and temperatures. Because of this, all I can offer is suggestions of the cooking time. You may need to adjust your cooking temperature up or down to hit your dinner time right (also plan on an additional 15 minute rest time before you carve).
At 235 degrees F your turkey will take 30 to 35 minutes per pound.
At 250 degrees F your turkey will take 25 to 30 minutes per pound.
At 275 degrees F your turkey will take 20 to 25 minutes per pound.
