This is great.. thanks for sharing!
What is your water source (you said you haul drinking water) I was wondering if using rain water or other?
Also you said it is solar powered... Do you heat the water with solar water panels and do you get water pressure via PV panels and some sort of pump?
I have a pretty rough/much less fancy version of this, and I know my wife would love it if I did something more like yours.
Nice work!
