or a Dual Alternator kit (DUAL ALTERNATOR KIT FOR 1997-2015 FORD E SERIES VANS WITH 5.4L & 6.8L & 270 amp alternator- $1300)
connected to an inverter would this be able to power most outlets individually inside the motorhome?
Is my math correct?
Approx the 320 amp @1200 rpm is @29 amps 120v & the 250 amp @ idle is 22 amps 120V
The dual alternator Kit with second alternator is a second addl 270 amps & 25 amps @120v, With a 20% reduction for losses they should still all be over 18 amps each.
In my mind this would be a better solution than the generator, as the generator is way too loud for sleeping or TV.
the only other issue I could think of is any damage being done to the engine if it was to idle for 8+ hours.
If the engine is running I also wouldn't need to run the roof AC or furnace (again both way too loud), my unit is only 25' total and the dash AC & heat cranks.
I also like the idea of replacing the generator with a large capacity battery.

You would also need a high idle kit or some other mechanism to kick up the RPM's from the standard idle of 700-800 RPM's. (That is part of the trick with a generator: when there is a call for more current from the generator the throttle is increased.)
