You will probably get more responses in the Class A forum.
I have a 100w solar panel on my roof. In late Spring through October, the panel gets enough sun exposure to allow me to avoid using the house battery cut off switch and still maintain my 440 AH battery bank.
I also have a Trik-L-Start gizmo installed that charges my chassis batteries from the house batteries.
The rest of the year, here in Sacramento, the 100w and shaded sun, forces me to shut off the house batteries.
I seldom shut off the chassis batteries between trips.
