Ok a little more detail and questions. It is a 1997 class a rexhall airbus. I am brand new to this and have no idea what inverter, etc I have. I do know that there are 2 batteries and they are brand new. Here are more questions.
1. Do I have to have the chassis turned off to charge the batteries when I am camping with no shoreline?
2. I am always plugged into shore power all the time at home. Will this harm my batteries? Do I need to be disconnecting them?
3. As far as recharging when I am camping with no shoreline I will only be using a couple lights, the pump when I take a shower or use the toilet and a fan.
