Propane storage
Even though I agree with Steve regarding the Origo (which I, a liveaboard, happily use), there are some practical, inexpensive options for propane storage. West Marine carries some long thin 6 pound tanks that fit perfectly into stainless fender holders, which, in turn, look just fine attached to your stern pulpit. Of course, you still have to do all the plumbing and connections, but you could easily have matching tanks on opposiste sides of your stern pulpit. I once knew a guy who had four! and they didn't look that bad.
