Preheat smoker to 225
Sprinkle the rub onto the hot dogs. Feel free to use a binder (mustard) to get the rub to stick - I had residual moisture and it worked okay.
Place on the grates for about 90 minutes, until they're looking dark and almost burnt.
Remove from heat, crank pellet smoker to 375.
Cut dogs into thirds, place into a half-pan. Slice up your 4Tbsp Butter stick and place around the pan. Sprinkle the brown sugar across the dogs and drizzle some BBQ sauce.
Place back into smoker for 30 minutes - giving the half-pan a stir every 10 minutes.
Remove and eat!
