Smoked Burger Recipe Wanted

[Jack D]

A relative just returned from Florida and raved about the smoked hamburgers she ate.  Apparently ground beef, pork and perhaps a bit of lamb but she wasn't positive on the latter.  Smoked for about 5 hours and served.  Claimed to be the best ever tasted. 
Does anyone have a proven recipe to recommend that I could try and duplicate?  I would have been leery about Bradley smoker temp getting high enough for hamburger but I guess after 5 hours of smoking they should be good to go??

thanks for any assistance out there.  Off in a few minutes to try and land a winter spring in Vancouver area (so far this year they've been avoiding my hooks!).

Many on here have done meatloaf in the Bradley. I have. Just crank up the temp. Personally I prefer to grill burgers over a wood fire or on the pellet pooper. I am not a big fan of mixing pork and beef except when you top a beef burger with bacon.
