As I plan my build I definitely need some help with planning the electrical. I am scouring all the other posts in this section to learn as much as I can, but figured I'd also layout here exactly what I need for electrical and ask for any advice others have. For more information on my overall build plan see the build thread link in my signature block.
Here is what I feel I want to do:
1. Obviously need to install brake lights and turn signals. I want these to be installed into the hatch itself, not sticking out from the trailer frame.
2. All lights will be LED unless there is some weird reason I shouldn't do that.
3. Two inside lights for the sleeping quarters.
4. Two lights on the inside of the hatch to light the galley.
5. Deep Cycle battery (maybe two?) in the tongue box.
6. Fantastic Vent (sounds like this is the brand everyone uses and recommends). Also unsure on how much a fan will drain the battery.
I don't really plan on much else. I do not need an ac/heater. I wont be installing a fridge of any sort. I want to keep my electrical needs to a bare minimum. Originally I had planned on not wiring anything except the tail lights and not even having a battery in the tongue box, and just using push-on battery operated LED's for lighting in the sleeping area and using a lantern for the galley. I have since changed my mind on that and hope to wire the above things.
I am not new to wiring but am by no means an electrician. I have re-wired many things around my house (all 120VAC and 240VAC). I have also built a control panel for brewing beer based on Kal's design from theelectricbrewery.com. However, I have never really done anything with 12VDC or used inverters.
As I said I would like to have everything hooked up to a battery in the tongue box, but would also like to be able to plug in at campsites. One thing I don't know how to go about is:
-Do I have the power always drawing off the battery and use the campsite power to charge the battery? or,
-Do I install an inverter and a switch to go between battery power and plug-in power?
My apologies for my lack of brevity. Being concise has never been one of my strong suits.
As always, any advice, experiences, et cetera are greatly appreciated.
