This is one I was really looking at to replace my way too hot Propane Furnace for my off-road camper...

I would create a couple of heat zones and use the hot water from hot water heater setup...
Aqua Hot has a slightly bigger model 200 as well... I also found a baseboard mounted heater you can run hot water thru it...

Something like this idea perhaps... This is as far as I got with this project but it has merit... For the smaller POPUPs and TT trailers maybe...
A Camper up in the northern parts of the USA came up with this idea and said it worked out great for him... Since the HOT WATER FLOW is in a closed loop it didn't require a whole lot of use of his propane to keep the water hot...

Just passing along giving you ideas??? I think this is called hydronic heating haha... A whole bunch of us was talking about this a few years back... It is so simply it's crazy...
I'm still working on my Battery upgrade haha...
