2021 E450 dual alternator
Does anyone have this package, or can anyone help with parts? Specifically with the gas 7.3L. My RV has the single 210 amp alternator, and I’d like to upgrade to a 240/157a dual alternator setup...

Let me chime in here with some thoughts:
1. Large and reliable alternators will probably become more important as lithium coach batteries become more common in motorhomes. Supposedly lithium battery banks charge fast - but only if one has a charging method that can deliver the high currents that the batteries will accept. For dry camping - especially when many hours of enough solar aren't available - a large capacity alternator driven by an idling chassis engine might be very useful.
2. Since any vehicle's alternator is very important, having two on board - when one or the other is getting used a lot for high current lithium coach battery charging year after year - to me would be a necessity for equipment backup purposes should one or the other fail when drycamping. Always have a Plan B for critical Plan A failures!
P.S. I think that emergency service vehicles often have dual alternators.
