Preheat smoker to 250°F (121°C). For oven, preheat to 300°F (149°C).
In a large bowl, combine ground beef, sausage, diced onion, cheddar cheese, cream cheese, jalapeño, and all seasonings with barbecue sauce. Mix thoroughly.
Stuff uncooked manicotti shells from both ends using a spoon or piping bag. Ensure no air pockets.
Wrap each shell with bacon, covering both ends. Use a second slice if needed.
Brush with barbecue sauce and place on a baking sheet or smoker rack.
Smoke for 60 minutes. Flip, baste again, and continue for another 60 minutes or until bacon is crispy.
Serve hot with additional sauce or dips.
