Depending on where you are in Texas, it is likely hot and/or humid. Either can cause false alarms especially if the heat is causing some out gassing. I had issues with when I did a lot of caulking in the bathroom, also once due to painting the plywood under the mattress and another time with due to a strong chemical odor from a plastic shower mat. The propane detector is especially prone to false alarms even when new but similar issues can cause false CO alarms.

Update: I brought the CO detector into the house and it went down to zero.
Took it back out to the coach and within minutes, the alarm is going off.
This is really strange.
I'm going to call Northwood (Arctic Fox) later and see if they can shed any light.

Remove the propane tanks and spray soapy water over the valve to see if is leaking. With the propane sorce removed from the camper, see if you are still getting propane alarms. If so, it is not propane but some kind of chemical off gassing from material in your camper.
If the alarms stop, you have leak in your lines that did not show up until your propane bottle valves stopped sealing properly. This will be harder to diagnose since the lines run to fridge, stove, water heater, furnace and generator. I would try and make a fitting so that I could run a low pressure compressor into the propane lines and then use soapy solution to look for bubbles. I know there is a dye you can inject into the lines and search for where it is leaking, but I have source this.

I called Northwood (Arctic Fox) and they're stumped too.
I'm going to replace the units and see what happens.

Is the TC plugged into power? I'm reading that battery outgassing can set them off as well.

Some auto shops have digital CO sniffers used for detecting CO in the radiator, possibly a smog shop as well (??) - you might call around for this…

I don't think replacing them is going to help. They went down when you aired out the camper. They went down to zero in the house. If they were faulty they would not have changed.
It won't hurt to pick up another detector and verify, but if the 3rd one goes off in the camper too, you can't just pass it off as a faulty detector anymore. One is possible. Two is unlikely. Three is unfathomable.

I agree, but I'm going to try. Then I'm going to start removing things.

The problem might go away when the pollen season is over.
And that might be why the alarm is okay when it's in the house, but not when it's outside.

go by the local fire station and see if they have a gas detector ( most truck companies carry them, engine companies usually don't). If they do it will tell them what kind of gas you are dealing with and it can tell where the PPM concentration is highest in your rig. They would prefer no to respond to dead or sick people in your rig and should be happy to help.
