We're doing a 6-nighter San Juan trip in a couple weeks with 5 people. We are bringing a two burner Coleman Stove and will use it for all breakfasts and dinners. I want to get a larger capacity propane tank and an adapter instead of bringing a bunch of 1lb disposable Coleman containers. From my calculations, a 5lb tank is ~5 of those Coleman cannisters, so may not be quite enough. I considered getting an 11lb tank instead, but my wife worries about just having one tank in case of failure. It makes sense I guess
My struggle is that two 5lb tanks take up quite a bit more space than 10 1lb cannisters. We just have one 14 ft raft, a ducky, and a SUP for 5 people... so I'll be hauling all the gear.
11lb = 9*9*17 = 1377 cubic inches
5lb = 8X8X13 = 832 cubic inches * 2 = 1664 cubic inches
1lb = 4X4X8 = 128 cubic inches *10 = 1280 cubic inches
Has anyone ever actually had a propane tank or adapter failure during a trip? It seems like the most common tank failure would be accidentally leaving the valve open. I don't want to bring 10 1lb cannisters, but am struggling because it would take up less space than bringing two 5lbs tanks. The 11 lb seems to make the most sense, but I don't want to worry about a single point of failure that will leave us propane-less.
