In two weeks we will be heading to the mountains where there is no power. We have an inverter generator we will use as needed. However, we are restricted to 10pm with running the generator. I have ...

I think everyone is asking what is the model of the "SMART CHARGER" you are referring to. This is either the smart mode on-board converter/charger for the trailer or perhaps you may be using a portable smart mode battery charger plugged into the 120VAC receptacle of the generator. To properly charge two 6VDC batteries as one 12VDC Battery you will need a smart mode charger rated at least 40AMPS DC output capacity. The Black and Decker VEC1093DBD 40 AMP Smart Mode portable charger is an excellent battery charger for this purpose and will indeed re-charge your 12VDC battery bank (two 6VDC batteries connected in series) in approximately three hours generator run time.
I would plan things to run down your battery bank no lower than 50% charge state which is somewhere close to 12.0VDC and then recharge back to the 90% charge state the next morning so that you can do this all over again the next day/night run off the batteries. Keeping your 12VDC Battery bank between the 50% charge state and at least the 90% charge state cycle will give you the best expected performance for your batteries. You can expect 12 or so of these 50% to 90% charge state cycles before having to do a full 100% charge state which will take around 12-14 hours to complete the required charge time. This insures your battery will be at its peak specified performance.
If you are planning on using your smart mode on-board converter/charger it will have to be 45AMP model if you want to re-charge the batteries in a quick three hour time. You will also need to have an RV30A-15A Adapter to be able to plug your 30AMP shore power cable directly into the 2KW Generator 120VAC panel receptacle.
Posting model numbers of both the portable smart mode battery charger and the on-board smart mode converter/charge would be useful for those on here to comment on your planned battery charge system...
