Can anyone tell me what would cause my RV propane tank to suddenly release pressure. This happened twice on my last trip. First time was when we were checking into campground. I was sitting in my coach (2011 Windsport) waiting for my wife to check us in when the propane tank let out a large popping sound followed by propane gas release.

I jumped out and shut down the system. We were not traveling very far the next day, so I left the system off. We were stopped at a re light when the same thing occurred with the system shut down.

I had the system checked out at Camping World, and they said they could not find anything wrong with the system. Can anyone shed some light.

Get the manufacturer name off the tank and call them directly. Sounds like it's overfilled or you have a bad high pressure release valve. Is there anything near it that could be generating excessive heat, like generator exhaust pipe or engine exhaust pipe, etc? I would consider that serious issue.

Gritz is most likely right, what was the ambient temp on both occaisions?

Agree with Gritz. With a full or overfilled tank, significant change in elevation can also cause the OPD to release.

RV ASME tanks (not DOT bottles) pressure relief valves open at 312 psi for RV and motor fuel tanks. That equates to 138 degrees F at sea level. If your tanks is up front near the engine or close to the exhaust that could cause the problem.
