I doubt that a dedicated charger will be much better than your current setup. If you have a single-stage converter, it’s more like a second-stage charger – Less than the full blast first stage, and more than the trickle of the third stage. If my battery is dead, the two hours I had to run my generator wasn’t enough, and that’s with my three-stage charger.

I’m not sure how well your batteries will handle being dual-charged if your trailer is plugged in to the generator *and* your charger is hooked up to the hooked up batteries.

Have you considered using portable solar panels?
