Carbon Monoxide Detector

I have owned the 180 about 5 months and have been having issues the last three trips w/ the carbon monoxide detector. Essentially, it starts going off when we start towing the trailer causing us to cancel the trips. After the second time and even though the unit is still pretty new including the detector, I clipped out the hard wired one and replaced it with a battery operated one. I also made sure the propane was off and even flushed out the blackwater tank thoroughly in case gasses from that was causing the issue. We then headed out on a trip this weekend and the battery operated detector started going off within 10 miles of my house? Has anybody had this issue? The propane is off at the tank and we have not used it since late June (furnace while in the mountains) so I am completely stumped as to what could be causing this. I do have an appointment to get a new hard wired detector installed in a couple of weeks (I was convinced the detector was faulty and that was causing the issue) so I will ask that they inspect to Frey and figure out the issue. Just curious to know if anyone has had this problem. thanks!

I'm guessing the CO detector is detecting exhaust from the tow vehicle. I have a similar issue, particularly after towing hard climbing a hill. It indicates an air leak, usually under the camper, where exhaust can get in. If the alarm clears when you stop and air out the camper that's a good clue. The Pods are usually very tight, but several owners have found big omissions in the sealing. Check the sealing around all pipe, wire and other holes in the floor including under the shower and behind the furnace and power panel. 

For general information, the hardwired device near the floor detects propane and carbon monoxide (CO). It is also sensitive to other volatiles such as perfumes and some cleaning products. Since auto exhaust contains CO it triggers the detector, as it should. The ceiling mounted device detects smoke and fire.

As an aside, although CO is lighter than air at room temperatures, it quickly infuses and mixes with air, so placement of the CO detector almost anywhere is appropriate. Propane is heavier than air so its detector is placed down low.

Didn't know that. As they say in Goshen: "Let no two Pods be built the same." 

Are you sure your battery was fully charged? If the charge voltage gets low, the cO alarm will sound..
