The black and gray tank has a bout two gallons of clean water and the gray tank which I check every week due to evaporation thru the vents from the heaters. Seems to work for me. In summer I am traveling about every other week so no special items other than running the vent fans to reduce humidity. Looking for any feedback.

I'm in the PNW and also in non heated garage. Look's like you have more than covered. I only plug my batteries to battery tender and don't worry about freeze. Has gotten down to about 17* couple times, nothing freezes in garage which is 40x40 insulated pole barn.
