Not there yet.

I will be entering my fourth season with the original 12 volt batteries in my Jayco and perusing this site I notice a bunch of you have proposed replacing the 12 volts with six volt batteries. If a person were to do that, does he have to replace the original convertor or will it work on the 6 volts ones like it worked on the 12 volt ones? I don't know what kind of convertor I have if that does make a difference.
