Looks like you have the process down. Final product looks good. Hopefully it tastes good too
I used to use a Firebird and Pit Viper fan to run my KK. I liked it but it blew ash all over and was just "more" than I wanted to deal with when using my KK. I bought it over a pellet grill or offset due to its simplicity. I enjoy it that way. Sold all of my KK gadgets about a year or two ago and haven't looked back.
I jab a RFX Wireless prove in the meat to monitor when I do overnight cooks. Other than that, I just use my Thermapen. No more fans, controllers, etc.
