Yes, as I said in my first post, I believe this is a 12Volt problem. Cleaning the battery is good stuff, always recommended. But if you don't find the problem there, then check the line from the battery to the converter. It might go through a junction box, or a circuit breaker on the tongue. Another possible place for corrosion. If not, then it's straight wire up and inside to the converter. From there, I would check connections and fuses. Will be off line for a while, others please feel free to chime in and help this guy!
