Interesting question. From an article on gas alarms:

“If you buy a residential gas detector system, make sure you get the right one, O'Shea said. Natural gas customers should purchase a detector that can sense methane gas, while propane customers should purchase a propane detector.”

So it would appear that a propane detector such as we have in our RVs would not detect methane, which is a component of sewer gas.

Over the years I have had all sorts of chemical set off the propane alarm. Those items have included hairspray, insect repellent, sulfurous emissions in Yellowstone, and caulk. The caulk was the worst. I used a large amount in the bathroom to add a slope to a small ledge. I had to disconnect the alarm for a great many weeks while it cured.

You may also get false alarms as the detector ages. The life expectancy of a propane alarm is about 5-10 years from the date of manufacture. Some seem to be overly sensitive or defective and give false alarms when they are relatively new.

A few years ago, a poster to this forum had a dog with intestinal issues. He said that the dog regularly set off the propane detector.

That may be dated information. It’s hard to even find a unit that doesn’t claim to detect both propane and methane. My suspicion is that they can only label them with a particular gas if it was tested by a standards organization for that gas but that most of them in general detect flammable gases and vapors regardless of the label.

I think the alarm going off, is likely the co detector. In that case anything having carbon monoxide would set it off.

Many times the propane and co detectors are incorporated in one unit.

Storing a bottle of Tequila, where it can move around/break is dangerous! Just when you really need it, you discover that you are OUT!

Not based on my experience. Every time I have had a false alarm the lights indicate it has been from the propane, not the CO, detector. I also have a separate CO detector. Except for using the test button it has never gone off.
