As does my propane furnace. And any other propane furnace.
It is hard to imagine the failure that caused this calamity. I suppose the burner tube could have been rusted through to the interior.
But, it probably takes a hard walled RV to buildup enough CO.
An SMB with the penthouse up would be difficult to buildup enough CO. The gas vapor pressures are high enough to cause the CO to flow through the softwall of the penthouse. Maybe the reflectix type materials used for insulation could cause a problem. Or a hardtop style SMB.
Before you ask, I worked for many years in a chemical analysis industry. We could (and did) measure the dissolved gases in liquids. It was incredible how quickly gases would permeate through seemily solid tubing and contaminate liquids that had been purged of dissolved gases. 1/32" solid, extruded FEP teflon would only slow down the rate. It took solid metal tubing to stop the gases from passing through the tubing.
