I was wondering if anyone has any input on my delima. I have two Honda 2000's hooked together. I am running them into a 30amp hookup on the outside of my enclosed trailer that goes into a breaker box inside the trailer. All the stuff that came on my trailer was 12 volt (power tounge jack, indoor light, exterior lights and powered awning). I am going to wire the inside for 110 with outlets, AC and flourecent lights. I think I will probably put a tounge box on and would like to put a battery or two in it and wire it so I can use that power source instaed of having to always have the trailer cord(12v) plugged into my truck. My question is, I am not sure if I understand how to do this portion of the wiring or what I need? How do I wire the battery or batteries so that the can charge? How and where do I splice in the current wiring. Do I need anymore equipment? I am not really concerned with converting 12v to 110v. I just want the battery for the stuff that is already 12v so I can use it when the truck is not hooked up or turned on accessory. Any help would be greatly appreciated.
