Mix the brown sugar, smoked paprika, garlic powder, 1 tsp salt and 1/2 tsp pepper and rub it all over the pork.
Slice the onion into the bottom of the slow cooker, set the pork on top, and pour in 1/2 cup barbecue sauce and 2 tbsp vinegar.
Cover and cook on LOW 8 hours (or HIGH 5 hours) until the pork shreds easily.
Lift out the pork, shred with two forks, and discard any big fat pieces. Stir it back into the juices with the remaining barbecue sauce.
For the slaw, toss the coleslaw mix with the mayo, the remaining 1 tbsp vinegar, and a pinch of salt and sugar.
Pile the pork on buns and top with slaw, or serve the slaw on the side for kids. Leftover pork freezes well for up to 3 months.
