RV gas detectors warn you of dangerous propane or carbon monoxide leaks before they become life-threatening. Propane is heavier than air and pools at floor level where leaks occur; CO is odorless and can accumulate quickly in enclosed RV spaces. Combination detectors that monitor for both LP gas and carbon monoxide provide comprehensive protection in a single unit and are required in most new RVs.

What to Know Before You Buy

• LP detectors mount low (propane sinks); CO detectors mount at breathing height—combination units account for both with sensor placement.
• Detectors have a lifespan (typically 5-7 years) and should be replaced when they expire—check the date on your current unit.
• Hard-wired 12V detectors are most common in RVs; battery-backup ensures protection when shore power is disconnected.
• Test detectors monthly by pressing the test button—don't assume they work just because the power light is on.
