Update to my previous post. Installed a 105a/h deep cycle battery and box on the tongue. Wired it to the 12vdc circuit. I mounted a 12vdc accessory jack/plug on the outside of the box. I can charge the battery during the day using a 15w solar panel, and then plug a 450w inverter for night time power during 'quiet hours'. I realize the solar panel will not fully charge the battery but it will help. I will only be drawing about 100w for about 2 hours a night. TV and satellite receiver, maybe laptop. Installed a led porch light and a flag holder. Can't go out for Memorial day without a flag! Especially being a veteran. Dummy me. I installed the battery box so close I could not crank the wheel jack. Figured out an easy fix. Extend the shaft for the crank to over the battery box. Live and learn. Put the name on the back of the trailer, NITUSHI . Pronounced, need- ushee. Means Little Bear in Choktaw. Getting ready for the 1st real trip with my rig, Memorial day weekend. (Birthday weekend also) Actually a week long trip into the Sierra Nevadas. Dry camping so I'll rent a generator this time. Buying one when I get the $$. Being I work in the industry, taking a satellite system with me. I'm going by myself so I need some kind of entertainment after the fish go to sleep for the evening. Happy Camping to all. Memorial day weekend.... Get out there and enjoy the great outdoors!
