Where a gravity furnace could work in a RV, not use electricity it would burn more propane, unless it was below floor level. A wall mounted unit would put heat high in the room, to pool at ceiling. With nothing to circulate it would take a lot of heat to get that pool down to knees. The fan blower reverses the natural flow in the furnace, so the natural flow in the room helps to heat it.
Exactly,we had one in a house when we first bought it..Worked okay just like the gravity furnace did in several truck campers and travel trailers..Those of us that have actually used them in cold temps,actually liked them and the lack of electricity needed...

The OP is looking for pleasing light and heat . LED produces neither.

So it is nostalgia thing?
Years ago, I had gasoline powered lamp.
It was original cool-miners light, what was cool as it had self-igniter (rare 40 years ago) and flame had double steel mesh around, so any methane presence would be indicated by internal blows, but without igniting gas around.
It was cool as hell, but over the years its practicality diminished and finally it ended in the garbage.
So back to my question. Why not slap couple of LED panels inside the old fixture and have it all without maintenance hassle and without endangering your life?

They used to have just a furnace without a blower that forced air out, kinda like a catalytic heater,that had no blower or electricity involved..The thermostat was numbers on the dial..LOL..When the number on the dial reached it's temperature,it went to just the pilot until it needed more heat...
The older campers had the propane lights/hand water pump/forced air furnaces(without blowers) etc because most only had one battery and RVing was nothing like it is today..
Old school wasn't so bad and everyone lived that followed instructions,just as today..LOL
I know what used to be, but that was called a gravity system. The heated air is lighter, so it flows out to be replaced by colder air. In the house I grew up in, if we closed the door at the bottom of steps, so the dense air could not come down, we had no heat in the upstairs bedrooms.
