Kelly, if you've tried all of the various options out there for making camp coffee and have settled on the percolator, what would you expect to be different about that Brunton? It's still nothing more than a drip coffee pot with a different heat source. I don't see the advantage in bringing along something that takes up more space, adds another level of complexity, and will undoubtedly make lesser quality coffee than a percolator.
Just because.
But if you want a reason then here are a few.
I don't like using my duel burner Coleman stove. Too big and heavy. Over the years I have been going lighter and lighter in my travels.
I like the idea of using the same fuel cans for my stove as well as the coffee maker.
I really don't like the Coleman coffee maker, it's a boat anchor.
My percolator is a little tippy on my backpacking stove.
Sometimes I don't have a campfire to heat my coffee by.
All of the above are just excuses to by the Brunton because nobody needs it, right?
