I'll join those who like having solar and would inclue it in a new rig. During the last 18 or so months, my rig was in storage without any hookups. I have visited it frequently and the controller has typically read 13.8 volts. So for storage absolutly fabulous. Water consumption is about average. When visiting I run genny after checking batteries, after that I turn on the tv while I spend a hour or so dusting and running the 12vdc appliances etc. Always have fully charged batteries.
We have spent ten days in mostly sunny weather in a partly shady site without hookups and used power like we would have in a full hookup site. Did not have to use genny for routine living. We have a 300watt inverter so when wife did her hair we ran the genny for about a hour total dry and curl time.
I love the darn thing and will as soon as I can, up grade to 400 watts and four GC2 batteries.
