Beware of upgrade kits that replace the lower portion, which is the converter part. Some are WFCOs (Ultra is one name WFCO uses) and some are 7300s (better than the 6300, but same single voltage at 13.8. Look for the PowerMax (or Boondocker) or PD replacements, which have proper converters to them.
Notice where you must either replace the 6300's DC fuse panel or "jumper" it so it is no longer a "split panel". If you replace it, then you are half way there to what you need to do if you get the whole new power centre, but that is a bunch of wiring work. Depends on what you know or who you know for getting that all done.
Or you can just leave everything alone and use a portable charger instead. You can also get a deck mount converter and use it instead of the lower portion.
With the 1991 Class C, I chose to use a deck mount converter and jumper the 6300's fuse panel, leaving the 6300 converter there but disconnected.
It makes a difference what to recommend if you go off grid a lot or always have shore power. If off grid you will want an inverter to wire in with the new converter. That means you can even get an inverter/charger as another way to do it. I prefer to have the inverter separate from the converter (in case one breaks it is less costly to fix that)
