Sharko,

You need to let us know how you use your rig to help with your answer.

If you primarily use campgrounds with shore power and are only worried about keeping your batteries charged in storage your current set up should be plenty unless your GPS draws a lot. Normally you would want to totally disconnect your batteries in storage but if the GPS is a priority you will want to keep it connected.

If you are considering boondocking with solar as your primary power source you need to do more homework to determine your needs.
