Why do you need a 6 volt battery charger?
You pair up the 2 6 volt batteries to make 12 volts, and use the charger built into your RV from the factory.
The advantage to a pair of golf cart batteries is they offer the capacity and water storage of a 8D battery in two lightweight 67 pound packages. If you ever moved a 130 pound 8D battery, you will know what I mean. It is nice they are 'light'. When I removed my 4 batteries and replaced them, I got a work out that day! They are heavy. But 8D battery is much more weight!
The portable chargers are not as good, and normally only rated at 20 amps or less for 24 hour a day duty. Many say 50+ amps start capacity, but will advise in small print to only have it in start mode for 30 seconds, then unplug it for 20 minutes. It really overheats the poor charger, and will put out 15+ volts for that time it is in the start mode, causing battery damage if you forget it, and let it stay to long in high output mode.
