I'm pretty new at this and I am not sure you can have BBQ burnout. I guess if you have the same exact thing every time you might get bored with it.
Change the meat, rub, sauce, or any other aspect of the cook and you have something new and exciting. Try a different filling for a fatty, or even use some veg. I hear smoked cabbage is good, I grilled one once with good results.
Heck you might even grill instead of smoke. There is a whole culinary experience to be had with cooking over live fire whether direct or indirect. Be creative and have fun with it.
If all else fails and the family does grow weary, give me a call and I'll join ya.
