I have a Northern Lite TC that has a carbon dioxide detector that has failed. It is mounted on the inside above the entry door. Instructions that came with the new replacement advise that since CO2 is heavier than air, that the unit should be placed near the floor.I've been using the camper for over 10 years, and the old unit was installed above the door by the manufacturer of the camper. The beds are located high in the TC, over the truck cab, slightly below the elevation of the detector. I'm wondering - where do other RV's have their CO2 detector located? Thanks MTBob

The LP detector for propane should be low near the floor, but the CO detector should be higher. Not sure there is a CO2 detector. Unfortunately, they also make a combo LP/CO detector, so wherever you put it is wrong. IMO have two single purpose units and put the LP low and the CO higher. With the ceiling fire alarm, that makes three detectors.

The standard recommendation for a CO (carbon monoxide) detector is approx 5 feet above the floor. A CO2 (carbon dioxide) detector is placed at floor level.CO is lighter than air and CO2 is heavier than air.

CO2 is the good stuff that makes plants grow. CO kills people. Why would anybody have a CO2 detector?

It’s also at the foot of the cabover bed area, which is another recommendation I remember seeing on CO detector packaging. They should be installed in the area you will be sleeping. :):)

Maybe to check their soda and make sure it still has fizz. :B

In our Class C, I installed one CO detector on the ceiling in front of the top bunk (next to the smoke detector). I installed another one on the wall near the ceiling in the back bedroom, and finally I installed a hard-wired CO/Propane detector near the floor beside the furnace intake, which is under the the oven/range.

First my humble appologies for having a brain fart and mistating the "Oxide". As you all correctly pointed out, the detector is for Carbon Monoxide, not Carbon Dioxide. What a bone-head mistake.
And, after re-reading the manufacturers instructions, mounting the "CO" detector near ceiling level appears to be appropriate... though apparently it also can be mounted in lower locations.
Sorry to have wasted your valuable time repsonding to a stupid question.

CO mixes so well with air that it just doesn't matter where you place the detector.
That's why the dual, propane/co detectors can be mounted near the floor.

Wasnt a stupid question. I learned a lot. Who cares if you call it co2 or CO. We all know what you were asking. My CO detector came from the factory on the ceiling and came from the previous owner without a battery. Need to get on that pronto.

We purchased a combination Smoke/CO detector to replace our old smoke detector on the ceiling over the driver's seat. We also replaced our LP detector with a combination LP/CO detector which is mounted on the wall near the floor in our hallway. That should cover our CO detector needs!

because it too can kill. internal combustion engine exhaust contains co2. think suicides in a vehicle. the OP had a truck camper...slide-in.

Again, you are talking about CO (Carbon Monoxide) not CO2 (Carbon Dioxide) which is the gas in soda water and all carbonated drinks.

CO2 can very much kill too, if enough accumulates to displace the oxygen. This is a very real danger in silos and some mines, among other places. Some of them would even be equipped with CO2 detectors for safety.

Suicide by engine exhaust is very nearly impossible with modern cars that are running properly.
