This is a very personal decision as no one answer works for everyone. HOW you camp has a lot to do with it.
If you spend most of your time in full hookup campgrounds, the dual purpose battery and standard converter (not inverter - whole different beast) is most likely just fine. An over night in a Wal-mart parking lot will not overtax your battery (normally about 75 amphours) in the slightest. The next day's drive to a full hookup campground will bring your battery up to snuff in a couple of days with shore power.
If you want to run your TV while at the Wal-mart; THEN your would need an inverter to convert 12 VDC off your battery to 120 VAC to run the TV. NOTE: NOT your coffee maker as a 75 amp hour battery would not last long enough to brew a whole pot.
If you want to run your airconditioner or make coffee then you would need a generator. 3000 watt is about right for a 30 amp camper; though some get by with the 2400 watt unit by watching what is on at the same time.
If you boondock a lot; your needs become very different and the standard equipment quickly becomes inadequate for the job. There are many good books on boondocking and you should invest in a couple to bring you up to speed.
When we talk about using a dedicated battery charger running off the generator, we are talking to folks who spend a LOT of time "off the grid" and need to keep their battery BANK (2, 4 or 8 batteries) fully cycled for maximum life.
