I gave a little though to a constant hot water module, but realized we would probably not be hooked to 120v most of the time and it is high wattage.
So, here is my plan, partly, after fixing the crack and other stuff. I plan on putting in two 12v deep cycles in parallel, with an inverter/charger while we are in a campground and a portable solar panel
for charging while we are not hooked up. Plus adding a 12vdc to 120vac converter. I am a ham radio operator and like to try new places, plus, I write and do digital editing for a living and like to work on the road, (why we have a motorhome), so I need electricity for down time (I like hiking too). Thats my current plan.
