Charging Strategy, 1994 RoadTrek
Hi all, I've been diving back into how to upgrade my battery system in my class B and was hoping someone here could sanity check me. I have a small 100AH 12V coach battery and I'm upgrading to a pai...

I think I've got this pretty much figured out, but I have a question that is probably pretty straightforward for someone who isn't totally new to this stuff:
It looks like the stock alternator on the 1994 RT is 120A. The documentation from the battery manufacturer (Vision, chinese brand) says that initial charge current is also 120A. That's perfect, right?
It seems like the right solution is, like you guys said:
1. A charger inverter (thinking AIMS Power PICOGLF30W12V120VR 3000 Watt) and just run everything in the coach from the inverter
2. To run the alternator charge line directly to the battery (and not worry about overcharging because the set point for the voltage won't cause problems, especially after the drop through the isolator)
3. To run MPPT solar directly to the battery as well (since it will turn itself off when it sees the charger charging) should I want this in a future purchase
And it seems like I can switch between 120VAC and 12V systems just by turning my inverter on or off (turning it on will start inverting to 120VAC and the existing converter won't hit the batteries directly, turning it off will show no voltage from "shore power" so the batteries will be hit directly).
Unless I'm wrong, of course. :)
