Hi Doreen!
We have been getting quite a few requests for this as it is getting to be about the time the Atwood detectors need to be replaced. Unfortunately, Atwood isn't around anymore, but we still have you covered. You will want one of the two I have listed below:
RV Safe RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - Black # RS54FR
RV Safe RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - White # RS34FR
Other than the color, these are the same part. They are larger than the Atwood you currently have (at least from what I could find as it's been a while), but they do come with two brackets to try and help with that:
Larger bracket: 7-1/4" long x 3-3/8" wide
Smaller bracket: 5-3/4" long x 4-1/4" wide
Any more trips planned for the year?
