I have a stove that I built last year for my 14x16 wall tent. I made it from an old water heater and scrap plate I had. It is sized in between the Cylinder Stoves Outfitter and Hunter model at 15.25x24". It has no problem keeping the tent warm in temps. down to 10 so far and heavy winds. I don't think it would be a prob. heating the 16x20 either. 5 sections of 5" pipe, legs, arrestor, poker and shovel, fire gloves and some lightered pine fit inside perfectly. I have the stainless cut out for a water heater but haven't got around to welding it yet.
