Final note on my BS by Memphis:
Seemed to have resolved my fears of grease fires. Two things:
1. keep the pit level. Tilting to one side or another, allows grease to travel down the grates to the low ends, and thus from there down the sides. On the Memphis if it drains down front or back, then it will be in the fire pot area.
2. Make sure the "flavorizer" assembly is centered so that dripping grease drips outside the divider wall and not inside for the same reason. The fire I had was due to this error on my part and also, to a damaged control that caused run away heat. Of course I will use a drip pan for large fatty cooks as added insurance.
Now I level the Beale Street for long cooks, and greasy cooks. Overall, very happy with the Memphis.
PS: One comment on PID controls. I think the pro explanations on how they work are misleading. We all know that while we see the "actual" temp matching up with the "set" temp when we are cooking, that the "real" temp is never steady and fluctuates up and down quite a bit. On both my RT 590 and Beale Street, this is as much as 20-25* each way at times. Answer as to why? is that the "actual" is the calculated average of these fluctuations. And if your PID is working well, then it is accurately calculating the average "actual". Otherwise, we would all have to watch the "actual" going up and down and be willing to not worry about it.
