I just bought an MES 40 last weekend. (I also bought a AMNPS that hasn't gotten here yet.) My problem is that the wood chip tray is too small. I will have to refill it numerous times during a smoke. I have read some old posts about a wood chip retro kit. I called Masterbuilt and they say that the retro kit they would provided me now is not any larger than the tray I currently have. Is there a way to increase the size of the chip tray now, as opposed to what posters said was available back in 2011 / 2012?
