I've read on here more than once that a battery charger plugged into a generator and then connected to the batteries is better than using the charging system in RV.
Is that correct or is it depending on what charger I have in RV? .
That... Was the right question: Here is the answer.
It depends on what charger you have in the RV.
Most modern RV's have 3 or 4 stage smart chargers (4th stage is equalization) and if this is what you have, and if it is the right size (Amps = about 30$% of battery bank C/20 rate) then this is the best way to recharge.
On the other hand if you have say 4 Pair of GC-2. (That is about 900 amp hours) and a 45 amp converter.. A big external may be better (That much battery can suck nearly 300 amps bulk mode)
Some RVs though (oldr ones) may have a Magntek 6300.. If you do, please UPGRADE your batteries will thank you (Progressive Dynamics 4600 series works.. Replaces JUST the converter part. Lighter too)
Some lower end newer units have the Parallex 7300.. this too is a single stage and an external may be faster.
other models you need to read the spec sheet.
