Thanks for the input John. Two weeks ago I called them and the person that answered the phone said they had the Slo Roller accessory in stock. I asked her to discuss with her supervisor if it fits the KJ Big Joe 2 as a retrofit. She came back on the phone after talking with her supervisor and said "yes it does, and would you like to order it". They were selling the item for $299 I believe. I told her I'd have to think about it first and hung up. A week or so later the item now looks "unavailable". I called BBQ guys and girl answering phone said they no longer carry the item. I then called KJ company directly and they stated (as you have clarified on this post) that the retro fit Slo Roller for the 2nd generation KJ Big Joe will likely be available no earlier that January 2020. No firm dates for release, nor pricing is known. Bottom line...I agree with J Setzler....BBQ guys doing some funky things....buyer beware.
