The carbon monoxide alarm goes off in the RV.
We have nothing on in there that would set a carbon monoxide alarm off. The propane has been off, the fridge is on electric at the moment, and the air con hadn't run in a while. I blow a fan up toward the detector and wait a few minutes.
It continues to beep every 20 seconds or so, so I go back to the house to tell the hubs.
As I exit the RV, the smell of SKUNK FUNK assaults my nares like nobody's business.
Back at the house, the hubs and I discuss what might have set the alarm off. I tell the hubs I haven't been tooting excessively in there!
I go back outside and by now, the SKUNK FUNK has lessened somewhat.
I go back into the RV, and the detector has stopped beeping.
Plausible Conclusion : The Skunk Stink was soooo bad outside the RV, it permeated INTO the RV - granted, we have a window that needs to be fixed/sealed, but still - and set the alarm off.
