ONE smart charge controller for solar, shore, alternator and gen

I have a 77 Argosy MH with 300 watt solar panels, solar controller and 4 deep cycle batteries. I believe my shore converter is original and I'm interested in upgrading to a multistage charger. With so many power inputs and controllers I'm concerned about charging conflicts. Is there a single smart charger/converter/controller product or method to manage and maximize efficiency, durability and safety of this system? Thanks.

There are combined units out there. The conventional approach these days is to use independent controllers. One advantage is the elimination of a common failure point. The other is that it's easier to optimize them independently than as a combination. Your shore power converter will be sized to match your batteries. Your solar controller will be sized to match your panels. That can get a bit complicated to juggle in one unit.

Charge wise, conflicts are not a big deal with modern devices. They pretty much expect there to be other devices running around.
