I emailed Masterbuilt about the new generation smoker. This is what they said: Thank you for contacting Masterbuilt. The model 20075315 is our newly designed Gen 11 smoker and is just like our other GEN 11 smokers but, all of the parts are replaceable for the newest smoker. The motherboard, internal wiring and all of that is not replaceable. That is the only difference in this newer model and our older models. Please let me know if you have any further questions. I was hoping they would say they made changes to the temperature gage to address the differences everyone has been mentioning, and the drip pan, although the pictures look like the drip pan was redesigned. I thought I would share. I haven't seen anyone post about the new generation yet.
