I have had to replace my regulators and hoses on 2 of my last 3 5th wheels. All were used and at least two years old. All different brands. Must be a recurring problem.

If the leak is the pressure relief valve there will be a very strong odor of propane. Happened to me.

You have a leak. If the regulator and pigtails are 5+ years old it would be OK to just replace them. I recommend Cavagna brand.

“This was one of my draw backs for fifth wheel trailers... My two propane tanks are directly under my front bed overhang haha.”

But on most TTs the propane tanks are 12 inches from your sleeping head.

If you have a high pressure propane regulator (not the dual auto switchover regulator) it may well be that regulator that is leaking. A not uncommon problem. But the relief hole is probably on the bottom side and hard to get soapy water on it to check for leaks.
I had the same slight but continuous odor several years ago. After thoroughly checking all connections, hoses, and regulators with soapy water and finding no bubbles, I finally replaced the high pressure regulator valve after reading a number of posts about them failing. After removing the regulator I could see that there was an oily residue around the small hole on the bottom. With the new regulator I have never had propane odor again.

I should have said a high pressure propane regulator IN ADDITION TO the dual auto switch over regulator. It is the small high pressure regulator that is known to leak.

Just went through the same thing and it is the regulator. Also did the hoses just to make sure due to the age of the unit. The cost was small compared to the damage it could do.

I'm going to disagree with the masses on this one. There is a vent on the underside of the switch and it's not uncommon to get some smells from that. If you can't find anything from a soap test and your tanks aren't going empty sitting with the valves open for prolonged periods I wouldn't worry about it.
