Avion camper heater...?

[d3500ram]

I saw the following ad on CL and the option about the heater caught my eye. Can anyone enlighten me on it as I have not heard of such an item. Is it a catalytic heater of sorts? Sure it is a TT, but there are some very knowledgeable Avion camper folks here... I am assuming that Avion is the same company for both TT and TC's (???)

This is the text of the ad with my emphasis of what caught my eye:

This is the one for you outdoorsman whomerver loves camping! 1967 Avion 24' in awsome shape for the age, will sleep 3-4. I have had this camper in -20degree ice fishing, elk hunting in 3' of snow and we stayed nice and cozy. The heater runs without electric,it is a drift style with termostat, all you need is a deep cycle battery & propane & your set for some awesome times . I have never used the toilet or water system, but I'm sure with a little TLC it would all work. The trailer has great tires bearings & brakes. Must see,asking...

So what's the story on this heater...?

Thanks for the photo. 69avion is correct in describing the heater. Its not an upgrade as I had thought.

That wall furnace looks like an original Duo Therm. It uses a fan to move the air across the heating surface. If it is like my original furnace, it is 15,000 btu. I think it has a fan because the ad mentions a battery. I'm still using the original furnace. All I had to do was get a new Therm-O-Disc.

The following is a photo from the inside... is that the heater next to the fridge on the right side?

You are correct that Avion made both TT's and TC's. However this appears to be a catalytic heater that was not OEM (to my knowledge). Its a pretty typical upgrade, I have one on my TC that I installed. Here you can see it on one of the cabinet doors:

Key word is 'heater' and not a furnace. It has a thermostat controlled burner, but not a blower. Many RV's of that era had similar type heaters.
