Depends on the independent charger. Most of the less expensive ones won't charge as fast as a good converter. If the converter goes into boost or bulk mode, and holds that to about 90% battery charge, that is as good as you can do without special monitoring.
Converter max output should be about 20-25% of battery capacity for fastest charging. With my dual 6V 232AH batteries, the 35 amp capacity of the converter is a little bit under-sized for fastest charging. But I never see more than 30 amps going into the batteries - and then it drops to 20-25 amps in a few minutes. The charging just tapers off that quickly unless you have a huge battery bank or really depleted batteries.
In my case, the OEM WFCO converter never went into trickle mode, and I suspect it never went into bulk mode (or exited bulk mode early). I replaced it with a Progressive Dynamics, and since then don't have to worry much about battery charging.
I don't carry a generator, as the batteries will run the 4 amp heater fan on a 50% duty cycle at night for 4 nights (plus other 12V needs) without recharging. That's as long as we stay in any one spot.
