Preheat the smoker to 225°F. Soak the wood chips in water for at least 30 minutes before using.
In a small bowl, mix together the brown sugar, smoked paprika, chili powder, garlic powder, onion powder, cumin, coriander, salt, and black pepper to create a dry rub.
Trim any excess fat from the chuck roast, leaving a thin layer for flavor.
In a separate bowl, whisk together the avocado oil, brewed coffee, and apple cider vinegar. Brush this mixture all over the chuck roast.
Sprinkle the dry rub evenly over the chuck roast, pressing it into the meat to ensure it adheres well.
Place the chuck roast in the smoker and add the soaked wood chips to the smoker according to the manufacturer's instructions.
Smoke the chuck roast for 6-8 hours, or until it reaches an internal temperature of 195-205°F. The meat should be tender and easily pull apart with a fork.
Remove the smoked chuck roast from the smoker and let it rest for 15-20 minutes before slicing or shredding.
