djdawg- i'm nervous about messing with a hose that doesn't say it's for potable water use for the fresh water... i don't know about the new ones i see on tv but i had an older one that worked fine for around the house where i wasn't drinking the water. on the hot water issue, if there wasn't much of a cost difference i'd replace it with a 6 gallon one. i've used the small electric on demand water heaters and they worked well but it would limit you're ability to bondock it. the bigger ones are pricey and i'm a cheap skate.
