Season them however you like or make up Bob Gibsons Alabama White Sauce to spread on the thighs after they are cooked. The recipe is simple and easy to find on the internet. If you have the grillgrates searing grates, I kick up the temperature to 500 degrees and sear them on the plancha side, skin down about 4 minutes till it looks crispy. Don't burn it. Alternatively, you could use a cast iron skillet to crisp the skin. I turn the temperature down to about 425 and move them to the regular grates, skin down, till finished. I take them off at 155 degrees which leaves them very moist. The rule of thumb is 165-180 but imho that's too much.
I’m doing some tonight. I usually set aside 3-4 hours, depending on ambient temp and whether I heated up the sauce before dipping.
Skin side down into a covered foil pan seasoned with Traeger Big Game Rub with a TBL of butter on each at 250* for about 45 minutes.
Onto the grill, skin side up with a dusting of TR Big Game to an IT of maybe 155* then dip in 50/50 mix of BBQ sauce/Apple juice a couple of times 30 minutes apart to an IT of about 175*.
I used the Competition recipe in the Traeger app last weekend and they came out great. Only thing I did a little differently is crank the heat up at the end after I sauced them. And put them right on the grates.
