I use a small dynaglo brick lp heater. I also have a digital co/lp detector. Some friends of mine use the same lp heater plus a ventfree pp fireplace. They also use a digital co/lp detector. None of our lp stuff even registers on the detector (and yes, the detector does work). I'm beginning to wonder if the "excess co" problem is the problem others make it out to be. I mean, I have spoken to many who use the appliances that are often pointed out as the ones to not use due to co yet are listed as being safe to use inside. These folks are all using various brands of co detectors. No one has had more than a 5 ppm popup and then only for a few seconds. I'm not too worried about my RV being "airtight". It's not. I have the excessive dust infiltration during dust storms to prove it.
