That is why your rig has a propane alarm, and why you should make sure it is always in working order. (And especially why, if it goes off, DO NOT IGNORE/SILENCE IT!)
Gas explosions are a real and present danger anywhere there is gas/propane.
It’s not quite as dangerous as that.
The Stoichiometric mixture of propane, the fuel / air mixture at which it can go ‘boom’, is ~24 to 1.
If we use a fairly small, 24’ long, 7’ wide, 7’ tall camper it would have an interior volume (24x7x7) of 1,176 cubic feet. At 24 to 1 that would mean there would have to be 49 cubic feet of propane, that’s nearly 2 cubic yards of pure propane vapour.
At far less than 10% of that you wouldn’t be able to breathe because of the amount of mercaptan in the air.
