Preheat your smoker to 225°F using fruitwood pellets for a subtle sweetness.
In a small bowl, whisk together the smoked paprika, garlic powder, onion powder, dry mustard, sea salt, and black pepper to create the dry rub.
Pat the ribs dry with a paper towel and apply the spice rub generously to both sides, pressing it firmly into the meat.
Place the ribs on the smoker grate and cook for 3 hours until a deep, mahogany bark begins to form.
Spritz the ribs with 1 tablespoon of the apple cider vinegar, wrap them tightly in foil, and return to the smoker for 2 hours until tender.
Carefully unwrap the ribs, brush the top side with the sugar-free BBQ sauce, and smoke for a final 30 minutes to set the glaze.
While the ribs finish, whisk the remaining 1 tablespoon of apple cider vinegar with the olive oil and toss with the shredded cabbage.
Allow the ribs to rest for 10 minutes before slicing between the bones and serving with the refreshing vinegar slaw.
