Could be from your black tank. When I am not going to use my trailer for more than a few weeks, I rinse out the black tank and "sanitize" it by filling it with water and adding a good amount of chlorine bleach, let it sit for an hour or so, then drain it. If you can't fill and drain like that, try just pouring a cup or so of bleach down the toilet, don't really need a whole lot.
Septic tanks can give off a "gas" smell, so it is something to think about.

Formaldehyde is in plywood, OSB, the glues in cabinets doors and in a few other materials in RVs. It's quite common in building materials. Here's a little info. for example. here.
Google RV + formaldehyde and you'll find lots of info.

Could be as simple as a failed air admittance valve under the kitchen or bathroom sink. Could also be the shower p-trap has no water in it. Grey tank odor can be pretty foul and not unlike a gas sort of smell. We've had to replace our AAVs 3 times and eventually got Oatey commercial grade ones (not cheap though).
If it was a propane leak, you'd expect your CO/propane detector to go off but your propane is off and no alarm.
How old is the RV? Formaldehyde definitely has a distinctive odor of it's own. It's usually dissipated after a few years. IIRC, some people are more sensitive to the odor.

Yes. It was used by "most" not all RV manufacturer's for years, and years. In Jaycos. The smell of a new one, was so bad you couldn't stand to stay in one long. Had to be aired out.

Propane.. I'm told the odor is "Essence of skunk" but I've smelled it. and I'd not describe it that way. Alas I know it when I sniff it. but... I can't describe it.
Propane is a colourless, odourless gas - what you smell is the mercaptan added to propane which contains sulphur and is the smell you detect as "propane".
