Hi there and welcome!
I don't have an MES30 I have the MES40 but I have seen MES30's up close and personal. You should be fine not cutting the roast at all.
As for temp and technique you will get many varying approaches mentioned so it's up to your preference.
Know that a pork butt/shoulder does not really care about the smoking temp so you will see people go any where from 225F - 275F. I personally do 275F because the butt doesn't care and it gets the thing done faster.
Also know that you will get better bark and flavor if you don't foil/wrap/pan/etc. Meaning just seasoning it well and let it go until it is done.
As for the Internal Temp (IT) the pork but is done when it is tender enough for pulling. I find mine to be in the IT area of 205F-208F where accurate meat probe placement matters a lot for the 3 degree difference so I run minimum of 2 meat probes in my pork buts (3 in my briskets). Use the temp as a guide and then go stab all over with something (I use long bamboo kabob skewers) and when the stabbing has no resistance AND the bone will wiggle right out then it is shredably ready :)
You are new to the MES so
understand the both the smoker temp probe AND the meat probe are going to be off. They are never accurate and this is a well known and documented issue with the MES. If you a wireless dual probe (or more probes) thermometer then use it, if not get one and I always recommend the ThermoPro Tp-20 for a good wireless dual thermometer but there are many out there that will work and possibly have more probes, which to me is a huge plus!
Finally, it is good you have both the
AMNPS tray and tube. Based on many reports here, helping guys here, and what I've seen in person the MES30 does not seem to like the
AMNPS tray to be placed inside the MES. The tube seems to have no issues with an MES30. If you want to use the tray it seems the mailbox mod is the only way to go for an MES30. I recently helped a guy via PM's figure this out with his MES30 so that is why I make the mailbox mod suggestion with the
AMNPS tray and the MES30.
Phew, this is a lot of info hahaha.
Oh one more thing, my pork butt/shoulder approach with my MES40 is the following:
- smoker temp 275F
- season the pork butt heavily (it is a thick cut of meat) with SPOG+Paprika. I don't do sugar which can burn and get bitter. Sweet flavor for me is added with BBQ/Finishing sauces after the fact.
- I put the butt on a roasting rack and set the roasting rack in an aluminum pan and put the pan on my smoker rack. This catches juices (if any) and greatly reduces or eliminates the need for smoker clean up. It also keeps the butt elevated and off the pan so smoke hits all sides of the butt
- I probe with 2 meat probes and when the lowest one reads 205F I go and stab all over with a bamboo kabob skewer to check for no resistance which = pulling/shredding ready
- I pull, wrap in 2 layes of foil, wrap in 3 bath towels, and rest it on the counter until it is time to eat. This is often 3-4 hours. The meat is still piping hot 4 hours later and easily shreddable and the meal is always on time (never late)
- I shred and add any juices back to it if any existed in the foil pan
- I may add more seasoning SPOG+Paprika if needed and mix in because again the butt is a thick hunk of meat so meat deep in the roast may need it. I find I don't often have to add much if any at all
- I let people add any BBQ sauce or finishing sauce they want on their plate since everyone is different. I like a good dose of a savory slightly sweet type of bbq sauce. Rudy's BBQ Sause is my favorite but is kind of a local one to TX. Some people want thick sweet, some people want vinegar types, some people want ketchup and mustard on it on a roll. To each their own :)
Ok that is enough from me as I have basically written an encyclopedia. I hope this info helps and best of luck! :)
