Roy,
FWIW we have been using a small Mr-Buddy heater plumbed to our onboard propane tank for the last 10 years in three different motorhomes. We run it 24/7 when it is cold and are still healthy. Our detectors have never come on except when I test them. We leave a roof vent slightly cracked open to satisfy the instructions provided with the heaters that a fresh air opening equal to a 3" diameter hole is provided.

Jim we do basically the same here using the single 1LB propane canister model MR BUDDY heater... I just got gun-shy reading all the comments from everyone about what the problems could be. Of course we have a couple of real good rv'ers on here that are CO Poisoning survivors which makes one really look at the MR BUDDY type heaters in another light. I have used them way back in my Tent camping days and run a many of 1lb propane canisters thru them. No issues here as well. There is just something basically wrong with cracking windows and vents and run a heater at the same time haha... Only recently I started shutting them down when we go to sleep at night... We like the covers and the zipped up sleeping bag halfs on the POPUP trailer beds... We definitely don't get cold haha...
I really want to install one of those CAT propane heaters that have outside venting capability... Talked with a couple of users -one with a TC floor space and he said it would run them out of his TC with good clean heat... I like that idea.
would look like this install...

I also have looked into doing the HYDRONIC type hot water heater and that would really be my best bet getting the somewhat smaller amount of heat we need. It is definitely very safe to use,,, This is all run in an closed hot water loop. Would have to experiment on how much propane will be needed to keep the hot water heater hot all the time... The only thing would be to run the propane a few times thru the night perhaps to keep the hot water at a thermostat setting since it is a closed loop. The two axial DC fans on it don't draw very much current as well... This is most likely the way we will go when we finally pull out the propane furnace... Will be something like this drawing...
