Would be interesting to see the fuel cost comparison in electricity consumed vs. charcoal cost...
While I applaud your outside the box approach, charcoal-fueled UDS's are already set and forget! And I'm with bluedawg on the power going out issue- Better have a generator handy so you don't ruin a cook!
Interested to see what your smoke producing setup will be. Good luck.
UDS, Akorn, Weber Red Head Kettle, Drum Grill, Gasser w/cobwebs all over it. I'm JD.
