Weird vague Freon smell entering rig

[doonkin]

Hey, I’m planning a big winter trip next week. My ‘aluminum falcon’ is sitting in driveway. Every morning I go in doing stuff n get hit by a vague Freon-ish smell. You know in you’re car when you kick on the cars air-con sometimes. Nothing is on- not the fridge or AC. I’ve taken everything out of camper that might be venting any odor- camper is 5+ years old n never gave off plastic-y smell before. I’ve opened every cubby hole/vent/trap inside n out w my sniffer n can’t smell anything- but still entering rig in morning I’m hit with undeniable-if vague chemical smell...am I mad?

Try pouring about a gallon of water/disinfectant in sink and shower p-traps. Air be escaping from tanks.

How full are your propane tanks? Empties or near, have a smell (suppose to).

It’s def not propane smell. Will try disenfectant down into grey water sewers.
What type of disinfectent -not bleach?

Honestly, I have no clue what freon smells like.

My guess dry p-traps, so adding water would be good.

Another thing, a dead mouse could be hiding somewhere.

Make sure to turn off the propane tanks.

Your roof tip AC could have sprung a leak.

It's not the frig, that is ammonia based.
