360 camera gives you an overhead view. Birdseye if you will. It is like an out of body experience looking down on vehicle. Makes parking much easier. I highly recommend. It is available on the pro with the Tow technology package. Rear camera is on when you back up and it also in operation with the other cameras around the vehicle for the 360 view. Obviously if you have a smaller battery pack the time you will power your house will be lower. I would still get the backup tho because with a little rationing I am sure it would ensure at least a few days of backup.You can switch it over anytime you like. When you bring in power to your home through your main electrical box you have to make sure the power does not leak out to the grid because it could harm someone working outside of your house. For example a utility company employee working down the street. This switch is part of what needs to be installed along with the charger. Hope this helps. I had the same question about the assist 2.0. I believe it is part of the Tow technology package and removing it is just something you have to do in the build when you add Tow technology. The added cameras under the mirrors make the 360 possible and is also part of the 2.0 assist.Hope this helped.
