Hello Brad, thanks for reaching out. We do have a carbon monoxide detector that can be used to replace your old unit. Here is what I recommend:

- RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - Black # RS54FR

This detector is for CO2 and propane so it does need to be mounted between 4" and 18" off the floor. It comes with a small and large bracket which cover most applications. It is also available in white as part # RS34FR if you prefer that. It has a 5-year lifespan which is standard for detectors.

Is the current CO2 detector mounted near the floor?

Hi Jesse, The one that I was inquiring about is mounted on the ceiling in the motorhome bedroom. I also have one for the propane that is mounted near the floor under the refrigerator, so I think I have that covered, I've seen one for sale like mine on E bay for $115. That seemed like a high cost plus if they aren't made anymore, what exactly are they selling? In any case, I would like to thank you for taking the time to answer my question! Brad Christian

@BradC I gotcha so our detectors are for CO2 and propane, or for just propane. Sadly, we do not offer one that is CO2 only and it sounds like this is what you are needing.
