First Alert Carbon Monoxide Alarm costs $24.99 at Costco

The cool thing about this device, besides the fact that it's guarding your life and the lives of your loved ones, is that it can be tested with your TV remote control. Just point your TV remote at the detector and it will tell you if it's operating properly. This is an inexpensive investment especially for older RVs that don't have one already installed.Helping you stay safe in your RV - Jim Twamley
