That's an interesting trick I hadn't heard of. I will try it. Also I added some 1" flat stove gasket material to the lid of my Treager to close off the air gap. I had to add a weight to the lid handle to pull it closed tight so I got a gal vinegar bottle and filled it with water and made a wire to hang it from the handle. Kinda redneck but it works lol.
It's still a timed algorithm instead of a PID. May work better but it's still limited in its ability to react to temp swings IMHO the savanna PID is much better
Next is a door gasket for me as well and a welding blanket for long cooks in the winter.
