I'm pretty sure I heard someone mention a pressure relief valve.
From the video it looked like the tank vented a small amount of propane
sporadically, indicating the tank pressure was too high.  Vent some gas,
valve closes, gets hotter, vents again, etc..

Or more to the point:

Does LP in an RV tank ever cause the tank to explode when tank exposed
to extreme heat for a period of time?
