Keep your rig's cabin monitored for two of the most common RV hazards with this combination carbon monoxide/propane alarm from MTI Industries. It hardwires directly into your coach's 12V DC system and flush-mounts into the wall or cabinet face, so there's no bulky housing sticking out — just a low-profile black unit that blends into darker interior finishes.
Whether you're replacing an existing 45-742-BL or adding CO/propane monitoring to your build, this alarm is sized and wired to drop into the same mounting cutout.
