Derrick, I would change a couple of things, maybe do three butts, use two “full size” foil pans, start two hours earlier, and rest two hours longer.
Honestly, the rest of your cook looks just fine. You have ample airflow, depth of drip pans is unimportant, catching grease is more important, don’t bother with liquid. I’d bump heat to 250-275. Pork butts are very forgiving and all you get with 220-225 is seven more hours of frustration.
But,
I’ve stated many times before, I’m lazy and like to touch fire off at 22:00 and go to bed. I’ve learned to just let the cooker roll. With a Searwood? Light it and go to bed.
It will be done when it’s finished and give a LONG rest to make sure the beer cooler is properly iced down, salads, sides and tables are ready for the feast. Pork butts are the best for that!
It’s barbecue, it has its own time management demands, don’t irritate the feasting with micromanaging!
It’s for fun!
To be clear, I am old school, charcoal, hand loaded in a WSM, pellet poopers are different but, I play bluegrass music, refuse to become “socially involved(aside from this gem among media)”, I hate cell phones, and am usually contrary! Just ask LMichalels!
