I have an Coleman Powerhouse Dual Burner Stove. Bought it back in '86. Doesn't get as much use as I would like for it too. (Sigh.) Still looks and works like brand-new. I'm one that really cleans his equipment before returning to storage. Troop198 you are correct though. My secondary burner is little more than a warmer that easily blows out. This stove is old school, only takes white gas and not unleaded. Don't know if I would want a dual fuel stove. I perfer the clean burn of white gas.
For my backpacking, I have a MSR Simmerlite. Name is misleading. There is not much control for simmering. Does put out a good flame that holds up to strong winds when using the screen. Can get sooty with during priming. Still it is lite and very sturdy.
As much times Troop198 heads into the outdoors, the troop might want to get a two burner propane stove.
Camp Chef Explorer 2-Burner Propane Stove First time I saw a large family with one at the state park, I thought "That's blasphemy." That was until these once strangers invited us over for pancakes on morning. I could force myself to live with that type of luxury.
