Have you seen this? It sounds pretty good to me. Except the price. $1000

A nice long hot shower would be nice but for that kind of money I can put up with quick shower.
It's an interesting concept for when you have full hookups.
But when boondocking or drycamping it's nice to limit the showers to minimal the "Navy Shower" rinse-wash-rinse-go. Less fresh water to haul, less gray water to dump!

I have two of these in my house (not the RV model). I never run out of hot water. You would have to have full hook ups or have the spouse changing out gray water tanks for your half hour shower. If you travel with your portable jacuzzi life would be grand.
