..just a thought...
I've had a NewBraunfels vertical (charcoal) smoker for about 20 years.
I finally got tired of "tending fire" and worrying about the temp, and the recovery when I had to open the door to tend the fire and water.
2yrs ago I bought a Brinkman replacement electric element ($30) and took out my charcoal pan. and since then I've added a cast iron griddle directly above the element and chip pan &a commercial cake pan as a bigger water pan. the griddle acts as a heat sink to speed up recovery when I need to add wood. so does the large/deep water pan.
I'm sold on electric smokers, whether they are vertical cabinet style or the pellet cookers.
the only thing I still have that's charcoal is a small portable grill I use when I go camping.
