Please help with solar and electrical questions...

Ok, so I just got off the phone with the dealer and cancelled my order for the $850 + solar package. I am going to keep the 11 cu ft 12v fridge option.

So now I just have the single 24v group 24 battery that the trailer comes with. I do see that there is a new feature of a "dual group 24 battery tray" so I could add another one and have two in my bank?

I do feel good about canceling my solar package order it allows me time to do some more research and see what my needs are for going off grid.
