Don, women often end up running the house in "shore life", but when it comes to solar/boondock, they should not. I saw a guy who let it be, as he was old and in poor health. His generator was on for many hours every day. With 200W solar on the roof and plenty of sun.
SMK, it's an interesting Shop-vac. Amazingly, the specs says it's only 4A. This is 40A out of 3*100 AH bank, 13A per battery. Not bad. One thing I'm trying to avoid is "on your knees" model - and this one looks similar. You can't work the floor with it without bending down, no?
