The Nu-way sets on the floor and in a teardrop floor space is limit. The sides of the stove requires clearances and you could really easily get something to close. The radiant tube heater would be by the ceiling radiating the heat waves down to heat the stuff on the floor. Being on the ceiling make is unlikely to get things to close.
{{the North Dakota oil towns}} close central Minnesota I would like to be able to ice fish over night in 0 degree weather. Body heat is not enough But a propane torch can be set to a low flame if desired Or a high flame if it gets really cold and windy. Battery power goes way down in cooler temps So a electric heater is out and I will not run a unvented heater in a confined space. The headache would take all the fun out of camping(fishing). I have been if fish-houses with unvent heaters It is not fun getting the headache (I may be more sensitive to it!!)
Sorry, your intended use (overnight fishing) is different than most of us who are looking for a warm nights sleep. We pre-heat, snuggle up and go to sleep. In the morning reach up, start the heater re-heating the inside space up to a comfortable temp to crawl out of the sleeping bag/covers. If I lived in the truly frozen north like you my way to get heat would be the bunk heater, blow the exhaust air from the camper into the battery box and it won't be too cold. Also remember that a gas bottle needs the gas to be warm enough to evaporate inside or the bottle will freeze up. I remember using an electric heater to keep a 100 lb tank from freezing up, to keep a salamander heater running in a cold hangar. (based on the little soldering torch bottle, a larger one shouldn't have the same issues)
For getting in and warming up many times overnight while fishing, I see why you want a major heat source...
We kicked the idea of the Nuway or a wood stove around on a thread recently, at least one member has a box that replaces the door on one side, the stove sits in the box and gets the needed floor space, set backs and thimble mounting from the box dimensions. I figured the box could be hung on the door hinges, just make it reverse-able so the box would stick into the tear through the door opening for travel.
Hope your design works out well, we are all watching..
