In a large bowl, mash the inside of the potatoes with the butter, sour cream, and half and half. If they do not mash evenly, warm them in the microwave for a minute.
Add the seasonings. Season to taste.
Add the remaining ingredients for the filling (reserve ¼ cup of shredded cheese for the topping) and mix well.
Add the filling to the potato skins and top with the remaining cheese.
Cook in a preheated smoker for 2 hours on 225.
Optional: increase the heat to 425 for the last 5 minutes so the cheese on top of the potatoes browns.
