OC, welcome to SMF! Glad you're here with the inherited smoker.
And don't sweat the lack of control with your Little Chief smoker. The less gadgets that are involved, the more your instincts develop. I've seen it time and time again that people blame the controller, thermometer, smoker, etc if the meat turns out bad. In most cases it is a lack of instincts. It has been proven you can smoke meat in a cardboard box (see YouTube). Heat...clean smoke...and time is all that's needed to transform proteins from raw meats to mouthwatering treats.
Start with something inexpensive and familiar while you learn how that baby works. You'll be a pit master in no time!
Enjoy the forum!
