Thanks for the good advice!
The Big Buddy has two regulators, one for each disposable propane bottle. Since both bottles empty my guess is the leak is at the on/off control valve, which isn't closing when the knob is at "off"! The problem is - when you have a problem with a Big Buddy just throw the darn thing out! You can't get it fixed, you can't fix it yourself and you can't take the chance of it exploding or catching fire! Truth is, I'm scared to even think about having something like that in my trailer! Thank heavens for the propane detector as the leak, fast as it is, is just slow enough that we didn't get a strong enough smell of propane.
