Any gas experts here?
Our Allegro is parked at the boat harbor, it's our home base for the weekends while I fix our houseboat.
It's parked next to a pond, which is at the moment, largely covered in moss. Along the shore is the typical 'water vegetation' like fragmite, bullrush, etc..
So last Sunday the propane detector below the bed starts going off. Did this a couple of times, then just reset itself.
Now, I have a nose for that smell they put in propane. I can smell a propane leak 1/4 mile away. There's no propane leaking.
However, standing behind the motorhome, within a small 'zone' was the distinct, but faint, smell of decomp. We didn't find the source, but people leave dead fish laying around all the time
--or it could've been a dead mouse, as I keep mouse blocks under the rig.
OR, it could the moss or vegetation...? Not sure.
I'm no scientist, but I believe decomp creates methane...
But that's not all-!
Earlier Sunday I was checking batteries, and found a cap off one of my 3 house batteries. The cap was nearby, so I topped off the battery with DW and went on my merry way.
So after the second alarm, I start lifting doors to see if I can smell propane, and when I open the batt compartment door, I find the battery I filled earlier smoking and bubbling acid all over the place as the case was now cracked in several places...
SO-- I never found any propane leak. But I did find possibly methane gas, and definitely sulfuric acid gas, which was right below the bedroom btw...
I'm kind of assuming methane may set off a propane detector, but what about sulfuric acid?
