Replacement Furnace

I am new to the Airstream world and this forum. Just purchased a 1965 23ft Safari four days ago. I knew it had a bad furnace, International Oil Burner model. I removed the furnace and am looking for a replacement. I am leaning towards a Suburban, however, not sure which model and size I should order. The old heater was mounted on top of a plenum which feeds duct work. The plenum measures 14 inches wide by 23 inches long. The new furnace will need to have a bottom duct to access the plenum and duct work. I have looked at the NT 16S, as well as, the NT20S. I have not been able to determine if they have bottom ducting. I know I will have to do some retrofitting. Anyone have experience with either of these units?

I have read several classifications in the forum and learning quickly. I did not see any posts with this info.

Thanks Stan

I, too, am interested in other furnace options for my Safari with a similar setup. I am especially interested in a furnace with a low amp draw for extended boondocking. Anyone have the "perfect" heating unit?

A 1965 Safari is a 22 foot Airstream.

For the small difference in price, most owners chose the Suburban NT 30.

It's the same size as the smaller units.

As RichHog said Palomino parts: 800-297-5830 has excellent prices.
This is how I did my furnace on a 1975 Tradewind. http://www.airforums.com/forums/f427...4sp-47264.html
Another clean install in a 1970 Overlander. http://www.airforums.com/forums/f427...0sp-41537.html

I installed a new Suburban NT 30 last spring in my 65 Safari. It was a pretty easy job. We just got home from a 3 day trip in northern Michigan with temps below freezing each night and highs only 33. The new furnace worked like a charm....Tim

The customer support at Suburban in Tennessee was very helpful to me when I needed info in replacing the NT-22 in my Trade Wind. You may want to give them a call before you buy a replacement. After talking with them I learned that I would need a 3rd outlet for the NT-30 to work properly in my TW. Since there was not easy way to do that, Mississippi winters aren't that cold, and I wanted to free up the space under the kitchen cabinet I went with a catalytic. When camping with shore power two small electrics keep the chill off.

But that does not circulate heat around the holding tank, which is necessary.

My PO took the furnace out when doing a total restoration on my Tradewind. Put in two catalytic heaters, one in the bathroom and another in the front. They sure heat up the trailer fast. I also have an electric one with a timer and a remote control so I can have a little heat when I am going to bed or click it on when I wake up. Keeps things covered if I run out of propane.
