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.
