Keep an ear out for propane leaks with this hard-wired 12V DC alarm from MTI Industries. It mounts flush so it sits neatly against the wall instead of sticking out, and it runs directly off your RV's 12-volt system rather than a battery you have to remember to replace.
A practical safety add-on for anyone replacing an aging propane detector or outfitting a build with LP appliances.
