just finished eating my first pork shoulder roast. It was amazing. We pulled it and made sammiches. 8lb boneless picnic roast. 10 hours at 240-250 degrees in my MES 40 with Mail box mod. Pulled it 195 IT and foiled in cooler to rest for 1hour. I tried the mustard and rub overnight that i have seen on here and the flavor was amazing. Thanks for all the ideas everyone.
