Sorry guys its one of those trips.

Well I had the ants inside the vents this morning. Now I started smelling propane outside so I went to the tank and heard a hissing sound. As I looked closer i noticed the regulator has a vent that had air coming out of it. It was also kind of moist around the regulator. The air stopped coming out of the vent when I shut the tank off. What's going on with it? I'm pretty sure its not normal. Your help would be appreciated. Just in case it makes a difference my coach is a 2013 352qs. Thanks again.

Sounds like a propane leak to me.

My guess - bad regulator. The moisture is condensation from cooling. When the liquid turns to gas it gets very cold.
It wasn't air. If you turn off the propane and it stops that means that it was propane coming out.

Thanks for the info. Is it normal for a regulator to go bad after 6 months of minimal use? Also can I still turn the gas on for a short period of time when we need to cook and them **** it right off when we are done.

Leaking propane gas is nothing to play around with. Getting a new regulator is NOT a big ticket item. Get yourself to a RV repair center to have it replaced as soon as possible. Have them pressure test the system while you're at it.

It's not expensive to correct.............the alternative of ignoring it IS!!!!!!!!!!!!

The regulator on my 2014 went out 3 months after I bought the rig. Of course it was when I was up in Mammoth and not sitting in my driveway.
