Propane shut off valve opens on its own

Grit dog, gennset was removed but drive could have caused it. So even if it is opening on its own, you are saying the leak detector going off is a down system issue. The tank is basically empty right now. If there is a tiny amount in it would it be unsafe to try a stove top burner? And in fact should I open it up to see if that leak detector comes back on? Doug

Presumably the leak detector is inside the camper and the valve/tank is outside, open to the air? Yes, a leak, if there is one, is likely downstream of the valve on the tank. (That could be leaking too? but not likely detected inside).

Since you're planning/needing to do work to the tank/valve it seems, I'd see what's left in it.
Turn it on and try to fire up the stove is a good way to tell.

FWIW, one can smell a very small amount of propane, but the concentration would have to be a major leak or leaking a long time and not vented to get to be enough to explode.
Or just unhook the line after the valve and vent/run out any residual gas in the tank. No smoking! LOL

I thought you had been using it regularly. My bad
You need to empty it anyway if you're doing rust work. and once it's empty you can easily replace the valve if it's giving you problems.

(I say easily, but I'm used to working on about anything that needs built or fixed, so idk what your comfort level is)
