I have the Nt-16 in my cube van, and I have the NT-20 in my 23'trailer(shop)
Awesome furnaces!
Since I'm often away from my cube van(home) for 8-12 hrs a day(working), I like to know when I get home in the middle of winter even at -20 F, that I will have a warm environment and that I won't have to contend with a frozen interior.
My water tanks are inside the cube van so if I keep the inside warm, there is minimal danger of freeze-up.
That said, I chose to locate the intake/exhaust plate at the rear wall of my build, the premise being with a non -ducted unit I would be basically sending the heated air towards the front through the central corridor if you will.
The Nt-20 in my shop was a ducted unit, but I plugged the ducts and installed a standard front vent plate on it.
This unit is actually mounted on one of the sides roughly in the middle of the trailer.
In both cases the heat dispersion is quite adequate for my needs.
I like to set the thermostat around 67 F in the van and around 60 F in the trailer.
As these are externally vented units, they are absolutely safe to run 24/7 while sleeping or not, however I do run CO monitors in the event of a heat exchanger failure.
I think there is a bit of loss involved in the ducted units, so I prefer the non-ducted ones.
I am entering my 4th winter with my NT-16, and I use it even in the summer when cold and rainy for instance, if only to get rid of the moisture.
The only real suggestion I can give is to be sure to mount it at floor level, and you might want to make up some sort of furnace filter for the air intake, depending on how you design the return cold air flow system.
You do need to make sure it can access cold air from inside, and that might be a place to use some ducts to grap cold floor air from front and back of the vehicle.
Good luck on it!
