Kevin,
Yes you still need 275 watts minimum.
Just parallel connect the additional panel on the roof.
I used to have 875 amp-hours of flooded batteries and used bank switching to save on solar costs, back when panels were "cheap" at $5.50 per watt.

I would prefer not to add an additional solar panel at the moment if possible. I do have a generator onboard and I do also camp at campgrounds with full hookups. With those two additional power sources do you still feel 275 worth of solar is needed?
I see you have a hefty battery bank. Admittedly I don't know a ton about solar. Would an additional solar panel connect to the one already on the roof or does it need to be wired down to the charge controller?
