Some of the people here are recalling incidents that took place a very long time ago. This article should be a good reminder that if you smell gas in your RV that you should figure out where it is coming from. I have various detectors and most of them were not expensive.
I cannot tell you how many natural gas and propane leaks that I responded to during my career. Many were actually odors coming from rotting garbage, but a few of the big ones required us to evacuate a lot of people, until we and/or the gas company could get things under control.
A couple days after I moved into my house I installed a CO detector.
The next night it went off.
I didn’t smell anything but called the FD and asked for a sensor.
It turned out to be a defective CO detector.

I would offer another course of action if you smell gas in your RV. GET TF OUT! If it’s not too bad turn off your bottles as you run by them and then figure out what to do next.
