I have not used a lot of different stoves but I used Sims Sportsman for over 30years.It heated tents from 12x15 to 16x 20. 17-18 pounds including nested stove pipe and in a canvas bag that fits into a pannier. Always put about an inch of dirt in the bottom before burning and after the season brush off and spray with vegetable oil.

If you have unlimited pack animals, one of the stoves with side oven,water tank, side shelf are nice,butt bulky.

I would be reluctant to use any stove with galvanized coating.

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
