On this truck we have a single 220AH alternator. Our next truck will have dual 220AH alternators I think. 2019-2020 ordering info not online yet for Ram 5500. They may also have an uplift option for heavy duty amperage draws as well.
How much we could draw for an inverter on current truck will have to be determined but the inverter charger can be set for almost any charging amperage so I am aware that currently 100+ AH draw may be too much. Not sure what the alternator reserve capacity is at normal engine RPM's
I think I will need to start playing with an inverter and see how it goes before mounting and permanent wiring.
