BSG and the Trailer tow and HD electrical group

[Foxtrot]

I dont recall this being asked before, so my apologies if it has.

Looking over my build sheet, it appears there is no change in cost (795 dollars) in the Trailer Tow and HD electrical group package when ordering the 2.0. From my understanding, the alternator is replaced with the BSG completely, meaning the 240A alternator upgrade might as well not exist. Now, I am still ordering for the built in switches and 7 pin harness, but shouldn't there be a discount on the group since there is no alternator to upgrade, or am I missing something?

Second question, any ideas on how the 48v to 12v system in the PPU is going to work? How much juice can I expect for aux electrical? The equivalent of a 220 or 240A alternator? More? Less? Will the system hate me if i winch while running an Arb fridge and some aux lights?

And lastly, what battery am I going to get?
600A in the 2.0 package
700A in the HD package
650A in the std (i assume not this).

Thanks in advance and sorry if this has been asked before and I missed it!

Battery as stated by the bud configurator at Jeep.com says 700 amp battery for the 2.0, not 600 amp. It does says delete alternator.
