Been away from these forums for far too long. Not sure why I have not been on as my passion for good BBQ still lives on, guess I just have not had the time. Anyway, on to the main topic here. I have an MES 40 that I have owned for about 2 years now. I love this thing for long smokes and use my amazin smoker with it most of the time. Based on some other posts, I checked out my smoker and I do have the smaller chip tray, so I called Masterbuilt and gave them my model number and they said that mine does not qualify for the retrofit. I asked if I could buy the parts and try to make it work, and she said they would not fit. Has anyone else called them and received this same response? If so, has anyone been able to do this modification anyway? I am willing to pay for the parts if necessary. I would love to be able to use the chip drawer for quicker smokes if I can find a way to get the parts and make the modifications. I have a big party coming up in the next couple of weeks and will be cooking for about 40, so will have all 3 of my smokers going, and would like to get this mod done before then if possible.
