If anyone would be kind enough to help me work through some of the electrical planning I would greatly appreciate it. I'm in the process of wiring a box truck which has the front half converted to a living quarters and the back half converted to a garage/work area. I've been trying to educate myself on how the electrical should be laid out and so far think this is the way I plan to do it:
AC - I have a Generac ix2000 generator the I will use for the AC. I plan to do like one of the other posters I saw on here and run power into GFCI pigtail and then into a plug strip with a 15 amp breaker built in. From there AC will go to a 5000 BTU A/C, an undermounted electric pressure washer and a 110v receptical in the garage area.
DC - I plan to have one deep cycle 12v battery or two Trojan T-105's. DC will power four 60w interior lights, 3 55w exterior flood lights, a 13" DC TV/DVD, and an iPod musical device with speakers.
Some of my questions are more specific about how to hook things up, switches, wiring, etc.
1. On the DC side, should I use the simple DC automotive-type toggles to switch lights rather than the switches normally used for AC or does it matter? If its a toggle, does it need to be enclosed in a box like an AC switch or can the connections be just pushed back into the wall cavity?
2. If I use extension cord for the runs do I simply cut the green wire short and disregard it and only use the black and white to go back to positive and ground?
3. Most of my wiring will run under the box. Should I protect the outside wiring in conduit or will the extension cord hold up to the elements?
4. I have a Generac ix2000 generator that I will use to power the AC and to re-charge the batteries. It has a 12v DC recepticle to charge batteries. Do I run wires off the positive and negating terminals of the battery to the DC outlet on the generator? Do I need some kind of a device to make sure that I don't over-charge and damage the battery?
5. On the lights, can I use any light if I put a DC bulb in it? Does it have to be wired with the positive on a certain side?
6. I found two types of bus bars at Academy. One is just a metal bar and the other has a bar for the negative and a bar for the positive with a place for fuses. Which one wold you recommend? (pics below)


6. Do I need some kind of GFCI protection on the DC between the lights and the battery?
7. On the AC, do I need additional GFCI (for the AC unit, pressure washer) or will the one on the pigtail be enough?
Let me know if you think I'm missing something. Electrical is not my strong suit.
