Hello everyone, We are brand new to owning a 5th wheel trailor. Ours came with only one battery. We go out in the middle of nothing where there are no hook ups most of the time. My husband hooked up two extra batteries for longer life. But to me it doesnt seem to be lasting longer. When I check the monitor it said fair in a matter of hours. Starting the generator does charge them but I thought they would last alot longer than they do. And does anyone know why you can't use the TV without starting the generator? Is there a way to change that? I hope my questions are not to strange. Thank you for any replys.
