can I set up trailer to have 2 batteries run different things

[TurtleMan]

I Have a 2020 vista cruiser 19csk the battery in the front runs the basics such as water pump,furnace,stereo,lights and I think usb ports. I am wondering if there is a way set up electrical to have the battery run the things as it does and have another battery run everything else which would be light the outlets. I have a goal zero 3000 that I use to plug into shore power to run the system however when its plugged in it runs everything I think and it keeps the battery on the front charged. I would like the goal zero when plugged into shore power just run the things the 12v battery doesnt however I would also like to be able to have when plugged into shore via 30 amp electrical run everything and also charge both batteries like when I am at home or a full hookup site.

Is that possible?
Thanks in advance
