1978 chieftain 26ft furnace?

[78chief]

Can anyone tell me what furnace would have come in my 78 chieftain? The previous owner removed it since it was a southern rv and living in mn and camping spring and fall I'm going to add one. And I thought it would be interesting the know what came from factory so I could look up the btu heat output and use that as a guid for the size I put in now. Any advice welcome. Thansk mike

I had the same problem with my 78 winnebago. I found a good condition replacement on eBay. I got lucky, I watched and hunted til I found it. I haven't fully installed yet til complete my cabinet,  but I set it where it once was. You can tell because how the vent outside is the same shape and size.
