I have a 2013 Heartland Big Country 3450TS. I just installed (2) 6V Trojan T150 golf cart batteries. I am totally new to the RV world. Yes, I am starting out big. I just purchased a 2016 F350 to pull this bad boy with. So, now that I have it at home and the batteries are finally working correctly, what should I be able to run off the house batteries? Also, what switches do I need to flip in order to get such items to work (i.e. ceiling fan in LR, lights, etc.). Just not familiar with this stuff. Any help for this greenhorn would be very helpful. Thanks in advance to anyone that responds.
