I've done crock pot pulled pork several times. I think you need to boost the red pepper flakes from a dash to a couple teaspoons. I'd double the brown sugar too. I line the bottom of the pot with sliced onions and bell peppers. I make a big pot of rice and warm a dozen flour tortillas. When it's ready, I pull the pork and plate it on top of the rice. Onions and peppers go on top, followed by a drizzle of sauce. Then everybody takes a tortilla, loads it up, rolls it and eats. We serve the cole salw on the side. YMMV.

It's nothing like a smoked shoulder or Boston butt, but easy and delicious.
