I do not know the specs on our alternator.
The PO installed a larger one say 100 amps.
Would we need to change our voltage regulator?
Lifetime batteries has what seems a nice one (LIFELINE GPL-1400) but would it work with the Perkins 4 -108?

There is sizing calculator also but I do not know the specs of the Perkins. I looked in the Perkins manual but came up empty.
