Hi have a GMG pellet smoker which I love. Thing is, I'm always afraid of running out of pellets in the middle of the night if I try to smoke a large brisket. I've heard that with an electric smoker, if the wood chips burn down it will still continue to heat and cook the food and I can add more chips when I wake up. True or false? ALSO....I'd love a recommendation on a moderately priced electric smoker (digital preferably) . Thank you!!!
