We have a X17z...
fridge is 2 way, gas/120... so my thinking of running on solar only was off...
but it looks like running on Gas/solar to run the electrics would work rather well.
Now just to decide if I just want to bubble gum/shoe string a small panel with blocking diode and "hide" it from view in storage, or go the whole enchilada and mount something more powerful on the roof and be done with it. As I said, we don't boon dock.. and the only time we did, the house batt held up decently. (Note, we installed LED lights.)
Good call on pulling the fuse for detectors and radio..
