Electrical help needed

I have a 1000 watt Xantrex pro inverter installed in my coach by the factory. It is a modified sine wave inverter. I want to replace it with a Xantrex Freedom 1000 watt inverter charger that is pure sine wave. I looked at the installation manuals on both models and the wiring diagrams and required wire sizes are identical. Can I do this changeout and merely shut off my currently installed converter by flipping its breaker off. Thanks

Unplug the coach from shorepower and unhook ALL coach batteries (chassis battery can remain connected but be sure nobody goes in and throws the emergency start switch while you are working)!

Make sure you remove power AT the battery.
