Hey all, Just wondering if anyone has any experience with building a plywood smoker enclosure? This winter has been especially harsh here in the Midwest, and I am thinking a vented plywood box around my Masterbuilt Dual Fuel would help it hold temperature. Unlike my old electric unit, the walls of this smoker are not insulated. I am fairly handy, just wondering if anyone might have some pointers. Thanks in advance, and stay warm!
