Solar is almost essential if you aren't connected to 110 volts for days at a time. You can run the genny for a few hours, but that will never get you back to 100% SOC. Solar is the ticket, even if you aren't boondocking. Day in and day out it pumps charge back into the batteries...and has a really good possibility of keeping you near 100 percent. I have a Trimetric and I know how much power comes out of my bank. If the specific gravity or voltage is lower than the Trimetric predicts, that just means that the batteries, while rated for some AH capacity, are really no longer able to store what they were spec'd for. Sure they will come up to a good resting voltage and SG, but drawing 25% will drop them closer to 50 or 60 percent. I will replace my 12 volt batteries with 6 volt golf cart units when I can't live with the ones that came with the coach. My experience with 6v units being able to hold rated capacity for years has been really good. 12 V units just aren't that good over time.
