Maybe I missed something but wouldn't a generator (3000W) sufficiently recharge a battery bank even without shore power?
You did - a charger that is powered by the generator. ;) Yes, your trailer has a converter with a charging circuit sufficient for charging a garden variety flooded that you don't have much invested in but once you decide to step up to multiple deep cycle batteries, especially much more costly AGMs, you really need to take a careful look at that converter as chances are pretty good, depending on exactly what it is and how well (or poorly) it's been wired into the trailer, that it won't be suitable at all for properly maintaining an expensive set of deep cycle AGMs batteries. Read that discussion I linked to earlier - you may not understand it all but it will get you thinking in the right direction. ;)
