Combine all ingredients except BBQ sauce, in crock pot or slow cooker.
Cook on low for 6-7 hours or longer if needed. The pork needs to be tender enough to shred.
When pork is done, remove from pot and shred.
Mix 2 cups of the juices from the crock pot with the BBQ sauce and bring to boil to reduce and thicken slightly. Usually about 2 minutes or so. Stir constantly.
Pour over shredded pork and serve. You can also mix all together and keep warm in crock pot after removing the cooking liquid first.
