Yup... my ProMariner has independant grounds. I wonder if they're all common
internally, but I doubt it. Maybe one day when I get a little free-time,
I'll try to ohm out the leads. Who know?

I'm leaning towards getting a Dual-Pro single bank for when I want to top
off the starting battery... have you checked the prices of three bank
chargers lately??? WOW!

I've never seen a modern onboard charger that does! Admittedly I haven't
seen every one out there, but the DualPros, the Guests, and the
ProMariners
(which also makes the house brand for BPS and Cabelas) all have isolated
outputs with independent grounds.
