Ok I'll bite... You could ha e an underquilt with the hoses already run in it... And the pipes already around the stove... Or just in a coil in your pack... Maybe the rolled up underquilt would roll up to fit inside the copper coil... A small head tank made out of a milk jug would act as a blow off area and a refill area... Think of it like a car radiator with your reservoir... But much less pressures...
Takes alot of stuff to put together and i think it would be too much stuff to carry around but if im car camping it could be a worthwhile venture.
Go to Heaven for the climate, Hell for the company.
