I have been gathering data using my new 'battery monitoring system' which has greatly improved the 'lack of data' I had, which caused batteries to drain previously.
My discharge runs about .15 A with battery switch OFF. If on, almost 1.8 Amps. I carry 2 80Ah batteries=160Ah total; So 2 amps reaches 50% discharge in about 80 hrs. with the switch ON.

Before investing in new power grid, I strongly suggest you monitor some typical trips and figure out you're needed usage. My history shows I can easily support 2 camping days with no charge, even with heater on at night(fan draws power). But whatever you do, be sure to size panels, batteries as a combined system so the complement each other.
