I do not follow. Do you mean an AC charger? Heck either way is way to small. You have 4 L16 370 AH batteries wired in series for 24 volts. Forget the Alternator Idea, my bad. Alternator is 12 volts. For an AC charger you want muscle to minimize generator run time. Something on the order of 60 to 80 amps.
RV system design questions?

The AC charger that I am looking at is a 50 Amp charger.

I am considering a 50 Amp charger for shore/generator charging and a Victron 12v to 24v charger for when I am driving. Charging from an alternator is not a good option for me as I would have to add a (24v) second alternator as the coach charging system is 12v.

OK the Converter and better than nothing. But how are you going to control it so it only turns on when the engine is running? Otherwise it will use your RV starter battery to charge house battery all the time destroying your starter battery in a day.MSEE, PEComment

Another question:
As this is an RV that will be parked and unused for periods of a few months at a time will I need to take any special steps to keep the batteries healthy?
I expect to water the batteries monthly.
What else should I be doing?
Thanks.

Just disconnect everything from the batteries except for the solar, and check water levels from time to time. Better yet take the batteries out and take them home on a Float Charger.MSEE, PEComment

Pull the fuse on the smoke alarm and or carbon monoxide detectors, if you have them. They will add to your battery's daily cycling. Still check the electrolyte level in the batteries. What I always did is leave the power center door open and left the fuses in a conspicuous spot so that they can be replaced when camping season starts up again. Make sure your panel(s) get sun. Even clean them, especially if flat mounted.2.2kw Suntech mono, Classic 200, NEW Trace SW4024Comment

You should download the Victron Solar Calculator spread sheet at least version 1.9 Its an awesome tool for sizing panels to their controllers. It now allows you to create about 10 custom panels that you edit the "Modules" tab with specs from panels you are looking at to determine their voltages and amps using different sized controllers. It was a real eye opener for comparing panels and controllers that can handle them. -Bill
