I have a Fast Eddie PG500 that I love.
When we moved I left my Tregger behind and got a PG500.
Love it. Much better machine....
Anyway, i have thought about lining the inside with unglazed tiles to add some thermal mass to help even out some of the temperature swings. Most of my smoking is done at the 225-250 range, low and slow... and even with the controller tweaked, it swings a lot.
Any thoughts on putting tiles wherever they will fit to add mass?
