We bought a 1984 26' 5th wheel trailer that was a repo 3 months old. WE used it all summer but didn't need heat.
It had a Duo Therm heater with a split heat chamber. The first fall camp trip was a 3 day event trout fishing.
The heat chamber was stamped sheet metal with a gasket. Later a tech at the dealer ship found out the gasket was broken.
Anywayz a trip to the emergency room says I had a mild case of CO2 poisoning. The wife wasn't affected and we both were in the camper in the same bed and at the same table for breakfast/lunch and supper. I remember the smell when we turned the heater on but I thought it was was burning off the new smell as the original owners didn't use it.
Why do some non smokers come up with lung cancer and some non smokers don't and both exposed to cig smoke in the same home.
In '84 CO2 detectors were rare to un heard of.
