Sand buggy where I live is about as useful as a snowblower!
My lines go up and down so maybe I'm ok. But, I got mine last September so maybe they had more than one supplier since that date should make mine "old" style. So far I've had numerous smokes (2-3 per week most weeks) in cold and hot weather, large and small loads (6 briskets almost 87 lbs this weekend in back-to-back smokes) and haven't had any problems yet.
