The problem wth bigger is better is that they get the tent too warm in the early night. Look for one that is the tighest and that you can control the inlet air the best.
Most will not burn all night until you get a good bed of ashes laid down after a few days.For longer burning, get a coal grate,and burn coal that you bank down.Learning how ot properly bank the fire down will get you longer burning times rather than the type of stove as long as you can shut it down tight.
