To answer correctly, I would need to know what you mean by a "6 volt system". RVs commonly use 12 volt electrical systems, but sometimes an RV will have two 6 volt batteries connected in series to produce 12 volts (nominal). If this is your setup, then, yes, you can charge two 6 volt batteries at once, just be sure to connect the charge controller to each end of the series, DO NOT connect to each 6 volt battery individually, because most controllers are designed to charge 12 volt (nominal) batteries or battery systems (i.e. two 6 volt batteries in series is OK).
On the other hand, if you truly have a 6 volt system, i.e an RV that runs from a single 6 volt battery, then you must not try to use a 12 volt charge controller and 12 volt-rated panel.

The Coleman 40W Folding solar panel is the ideal choice for charging any 12 volt battery. This product is not designed to charge a 6 volt battery system.
