Bought mine from campers village. Standard thin walled stamped stove. I’m happy with it for the price. Kinda a throw away stove get 5 years and toss it. Did not like the flimsy legs it came with so made my own stand for it. On the upside it’s light to move around. As long as they are in good shape it is easy to control the heat but as soon as they are damaged gotta go. Found myself with bad bronchitis just after hunting one year and realized it was from the lid being damaged and to much smoke in the tent !!!
I had welder make me one, used a old compressor tank, metal, works great just a bit heavy, but in -30 plus temps, still hot in the morning, no flame needed to fire it up again.
The old "Airtight" heaters were great when in tent, hold fire all night. However found not nice to pack in truck and quad trailer. I like nice square heavy walled heater that you can pack pipes inside and nice to pack in truck. Also flat top nice for cooking.
I bought a 20 inch air tight from Campers Village more that 20 yrs ago. I always put a pile of gravel in the bottom before every hunt. It is still solid after all these years.
I have a 12 x 14 old forestry tent. I only wish I bought the bigger model back then. Bigger chunks of wood, more room, less stoking during the night.
I have been wanting to build one but our moose hunting area went to crap so we have not been out to moose camp for a few years. This is the style I have and it is light and works great.
