The interior electrical all seems to work well enough so I would prefer to leave it alone and take care of all this inside the rear hatch under the beds. Can anyone elaborate on this or give a diagram of everthing one would need to bring this into the 21st century? All that currently exists is a old screw-type fuse box and a plug, so I'b starting from scratch. What would be the best way to go?
New Circuit braker
Univolt
Two batteries
Propane generator.
Thanks!

If you want to do it with little compromise, then some interior and inner skin disassembly will be necessary.
I would just start over from scratch. Start with a new 120V 30A city power cable, going into a small fuse panel with modern circuit breakers.
I suggest three of them, a 30A incoming, and 2 15A outgoing. One 15A circuit streetside, and one 15A circuit curbside. Leave room for a 20A breaker for future A/C use, if necessary.
The
12V system typically starts at teh batteries, which are fed and maintained by a modern converter/charger. this uit converts 120V A/C to
12V D/C and simultaneously charges the batteries in the trailer. A provision in the wiring to the tow vehicle also makes charging while driving possible.
All ightsd and fans could be
12V DC powered, then the basic functions in the trailer will work the same, whether plugged in or while being off the grid.
A Generator can supply power to the trailer via the city power inlet, essentially chargin gthe batteries and supplying power to the 120V outlets.
In a nutshell, that's how my 63 Overlander works after having been completely re-wired.
