I purchased a Black & Decker smart charger from Walmart. It is computer controlled and knows what the charge rate should be and it does it in different cycles. It will even tell you if there is an open or shorted cell. It was well worth the $60.

I currently have a solar system/inverter installed. It puts out about 6 amps to the batteries in full sun. Hardly enough to keep the batteries charged. I don't think there is enough surface area on our trailers to build an effective system. You would probably need a 30-50 amp system to keep the batteries charged enough to run everything but the A/C.

Did you lose the Hi/Low fan control for the A/C?
