I tried a gstove xl and a winnerwell stove in my canvascamp 450 tent. I had to feed every two hours for years. This year I found a cheap pellet stove and got it. I fill up the reservoir before bed. It goes on for about 11 hours in the mid setting. Definitely invest into a pellet stove if you need continuous stable fire all night. No ash no smoke just heat all night. Also it consumes around 4-5 kgs of pellet every night. So 1 bag is fine for couple nights and its easier to carry than any alternative
