Hello all, will be heading out for our annual 2 weeks dry camping with a new trailer this year, with 2 6 volt interstate batteries. On my old 23b hybrid, i used my 2000w yamaha to charge the 12 v battery with a portable charger. With the new camper having what i believe to be a better charger/converter, would I be better off hooking the generator to the camper via the shore power cable and use the on board charger, or go with a portable charger? thanks for any input, as electrical isn't my specialty.
