Dualies with a camper on their back need the juice for charging the house batteries.

If I'm not mistaken I believe that the Rapid-Heat Supplemental Cab Heater requires a upgrade alternator since it has electric heating element that comes on before the engine warms up. By the way I have a diesel and I have cabin heat before I can back out of the garage.

My 2015 2500HD Duramax w/ snow plow package has the mandatory dual batteries and an HD alternator ( only one). In addition, unless a very heavy wire is run from the engine compartment to the 7 pin Bargman ( not the OEM wire) , it doesn't matter how many alternators you have. If you are drawing 20 amps on that cable you will get enough voltage drop to make it difficult to charge the RV battery no matter how many amps are available.

Minimum required equipment for Snowplow Package includes 157 amp, heavy-duty alternator (6.2L). Optional: Dual alternators 357 amp (6.7L diesel). This is what Ford says.................

You only missed one part. Lariat and up models got the 200A standard. I elected to just leave mine with the standard 200A. Less weight and I don't have a large electrical demand. I do not have the plow package on mine either. Salesman thought I was nuts because it's only $85, but every dually I saw with the plow package sat nose up with minimal weight in the bed, and I didn't want that.

I think Flybob nailed it, there's really no gain going back to the RV with the factory wiring. If duals makes you feel better go for it, but I don't see the need. Now most of the additional lighting being added to trucks is LED anyway and they pull a lot less amps than the old incandescent stuff.
