I got the house battery installed today. I want to again emphasize that this is a temporary arrangement just to get me through the Big Bend trip in 2 weeks and will change once I get a permanent dual battery setup. I decided to go with just 2 LEDs for now and have them both tied into 1 fuse so instead of a dedicated switch that I would wind up moving later I'll just pull the fuse when I want the lights off and put it back in when I want the lights on. I'll also pull the fuse for the cigar ports as the extension I have for the tent has a constant draw for illumination around the plug. One drawback to running the inverter when driving is the radio noise it causes. Luckily you can't get much on the radio in Big Bend so if I want to listen to something I'll just use the CD player.
