BTUs needed for a 1961 Ambassador

[Studioman]

This seems to the simplest to make a new plentum for to adapt to what is already there.
Is 16kBTUs enough?
For $350, it seems like a steal to me and right there in my budget just above of what I wanted to spend for a used one...
Opinions?
Suburban Furnace Nt16s Series Ducted - 16,000 Btu-pplmotorhomes.com

My Argosy 22 came with a 16k btu furnace originally, but it was missing. I saw that price yesterday and called PPL. They told me that the NT-16 was discontinued, and that there was only one left in the country. I bought it.
I guess we'll see if it actually arrives. PPL has shown other items on their web site that I've ordered, only to find out they're long discontinued.

16k BTU does not sound like enough to keep you warm in an old 28 footer with outside temps below 40 F. I installed a 30k Suburban furnace in my 1966 24' Trade Wind, however I elected to use under floor ducts, so I will loose heat in the "basement". Most Airstreams with under floor water tanks have heated tank cavities, using more heat. The NT 30 Suburban furnace seems like a very popular model. My trailer had a 22k BTU unit in it before the replacement.

A 1500 watt electric heater does an admirable job on cool mornings, like 50 F.

FWIW, my 24' Terry has a 20k btu furnace.

Our '69 Tradwind was spec'd with a 25,000 b.t.u. floor ducted furnace .

Airstream still spec's 25,000 B.T.U. in their larger trailers.
