Selling my Hunsaker charcoal basket and vortex plate for the 18.5 WSM. Works great but I prefer something where the ash can fall down and make cleaning the grease in the bottom easier. $75
Maybe you just need a basket upgrade Marc.
My wsm came with the Hunsaker diffuser when I got it.
It works well with my Arborfab charcoal basket.
The stock basket doesn’t come close to the Arborfab and is messy af.
