… Such as it is, as of Dec. 14, 2018.

Since the camper has been gutted, what electrical (lights, fan, furnace blower) wiring was damaged, missing or suspect, I decided that it was all to be replaced. That included:

• replacing the power converter (shore power to 12VDC) with an upgraded, higher amperage unit.
• Replacing all branch wiring to lighting etc.
• Adding a volt/ammeter in series with the battery to allow monitoring its state.
• Maybe adding an inverter to allow some minor amount ot 120VAC capacity being sourced from the batter(ies)
• Adding new batteries, as the camper came to us with none.
• Add new primary battery wiring (battery to converter).
• Adding proper fusing

At this point, the following is known or decided:

• Converter will be a Progressive Dynamics model PD4575 power center, with built in fusing.
• Primary wiring (running from battery box to power center) will be #4 AWG
• volt/Ammeter will be of the shunt type, with a 100A shunt.
• Batteries will be two 6V golf cart type deep cycle wired in series.
• Branch wiring will be #14 AWG stranded
