I just went out for the first time with my new 2 6v golf cart battery set up. What an improvement over a single 12v! It was a 3 day two night trip and we could have gotten by without recharging at all. And that was not using power sparingly either. Listened to the radio for a while, my daughter watched a few cartoons, water pump usage including showers, ran the heater at night, even ran the amber porch light at night for a few hours. The lowest it got was 2/3 full on the battery level indicator inside the trailer. I did run my generator for two hours on day 2 just to charge them back up. I am going to try and be good about not letting them get lower than 50% SOC. It seems to me that I would be able to camp for extended periods of time with running the geni about 2 hrs a day or probably every other day if I used power sparingly. I don't like running the generator more than necessary which is why I upgraded to the two 6v's.
My experience this trip was a perfect example why. My wife daughter and I headed out to a local reservoir dispersed site last week. We were camping on a Mon,Tue,Wed and it is quite a long bumpy dirt road to get to where we were at. We had hoped to be all alone, and we were when we got there Mon Morning. A couple hours later another person showed up with a TT and parked maybe 50 yds from us and immediately cranked up a loud @%$ generator. I thought it was strange that he would show up with dead batteries cause it certainly wasn't warm enough to need the A/C. He proceeded to run that thing for 21 HOURS STRAIGHT! I can't tell you how annoyed we were. When he finally left the next morning I could still hear the droning in my head. I was watching him when he pulled out and I noticed that he had NO batteries on the tongue of the trailer. I cannot believe that someone would pull up next to others camping and run a generator for all of their electrical needs, it boggled my mind. They even left it running when they were down at the water fishing for hours at a time.
