Add smoked paprika, ground garlic, ground mustard, cayenne powder, brown sugar, kosher salt, chili powder. Rub spices all around the pork and completely cover.

In a medium sized bowl add bbq sauce, water, and apple cider vinegar and mix until well combined.

Add yellow onion to the crockpot. Then place pork on top of the yellow onion. Pour bbq mixture into crockpot. Place crockpot lid on top and cook for 8 hours on low.

Shred cooked pork using 2 forks. Scoop juices from crockpot onto shredded pork to moisten. Drizzle additional bbq sauce for more flavor and mix.

Serve the pulled pork with toasted brioche buns and coleslaw to make sandwiches.
