Planning 12V Circuits

Hi,
I'm getting ready to wire for the 12v circuits in my gutted Tradewind and want to make sure I think of everything. Here's my list:

Fantastic Fan Front
Fantastic Fan Back
Furnace
Refrigerator
Water Pump
Bathroom Exhaust Fan
Refrigerator "helper" Fan
12v Power Supply Outlet
Interior Lights (LEDs mostly)
12v TV
12v Radio/CD/DVD

Please let me know if I'm forgetting something or otherwise should plan for something (the Fuse Box I purchased has 12 Circuits/Fuses).

One other question: Is there a way to power the Running Lights w/ my converter so I can run the lights when parked? It seems "odd" to just tap into the Running Light wire w/ power from the converter when in theory the lights could be receiving 12v from 2 directions - the vehicle and the converter . . . which I have a similar un-educated view of the converter wiring diagram in which, in my small mind, a 12v device would be receiving 12v from the house battery and 12v from the converter . . . how does the electricity know to reverse direction and start charging the battery instead of sending 12v x 2 to a particular device?

OK, well thanks for any help/thoughts you can give me.
MarkR

The easiest way to power up the running lights while parked is to use a jumper cable on your 7 way plug, don't recall which two terminals. But one is the power feed the other is the running light circuit. That way you can keep the circuits the way they are supposed to be.

Exterior [entry] 12V light. I like to add a 12V charging bank, 3 slots, somewhere out of the way so folks can charge their stuff and I'm not tripping over it! I do the running lights on mine. I use one of the circuits in the 12V dist. panel, to a rocker switch w/glow lite, then through a diode for one way power, then tap into the running lite wire. On the one I'm doing now I'm adding a 12V aux plug and speaker wire jacks just in side a curbside lower hatch door for outside use.

Sure, just run the wire. That's what I did (I had an extra switch that wasn't wired to anything). The risk is that if you leave the switch on while it's plugged into the tow vehicle - don't do that. I have a diode ready to wire up so that the vehicle's lighting circuit doesn't try to power my camper, but I haven't gotten around to installing it. If you want to be extra careful, use two diodes - one like I describe there, and one on the wire from the umbilical to the lights.
