The biggest problem I had when I got rid of all my charcoal grills and got a pellet grill and a gasser and my Smokin-It #3 was just getting used to having nothing to do when the meat is cooking. Pick your rub, pick your wood, plug em in, flip a switch and go find something else to do.
Of course, I didn't let the little lady know that they don't need any tweaking during the cook though
I should have sold my off-set years ago
