Battery Charging/Corrosion questions

As per usual I am here to ask for assistance:

So currently I have a 30amp outlet in my garage and my Camper stays plugged in at all times. Also, when I do go out I have it plugged in at the site at all times. BTW I have a two battery set up that came with the trailer. Seeing as how I don't boondock I am likely to just store one and be rid of it. But I don't want the corrosion to jump to the other battery if the cause is a power issue. Or ruin my batteries. So...

1. I have read some people say this may be the cause of my corrosion? Or could it just be some water getting in there?

2. Should I disconnect my battery when on house power?
a. In order to do this do I remove all wires, just the ground, just power??? Or just unhook the cable that leads to the trailer?

3. Somewhat battery related. Is there a way to get power to my outdoor 120v fridge while travelling?



Thanks!!!!
