You're not wrong, we could probably use a non-marine regulator, wouldn't be much different than what we could do by hand right now tho. Few would want to make charge adjustments themselves, but also we dont rely entierly on our alternator to charge our batteries (solar does that). If we'd have to do it often, I'd reconsider this choice.
But yes, there is some risk. Gatta pay close attention.
Seems like marine regulator designs are more complex, accurate and adjustable.
