I love brining fish and smoking them on Apple but I have failed to get a good Traeger — I just use a pill shaped charcoal smoker and its a lot of work.
I also have a charcoal smoker grill, but living at 8.500 ft elevation it is difficult to get charcoal to burn with enough heat to cook well except for just grilling hamburgers or steaks, certainly not for smoking a turkey. The Traeger has a thermostat and I find I need to run slightly higher temps than recipes call for because the thin air has less thermal mass and cooks slower.
