Dueling Solar Controllers?
My question for the TC collective, has anyone noticed any efficiency degradation in amp output when both rooftop and the solar suitcase panels (on separate controllers) are used concurrently, on the s...

They will add their amps ok at first in the morning but then it gets complicated. The ViewStar has that fixed EPSolar charging profile where it gets the battery to Absorb voltage (for AGM as set by you) then holds that for two hours then drops to 13.x (AGM setting) Float.
The Bogart controller is different ISTR you can set voltages? So set that one as close to the ViewStar charging profile as possible for the longest period in the day where they both have the same charging voltage.
Any time one has a higher charging voltage than the other, the lower voltage one will not put out any amps at all to the battery and you are on just the one.
EDIT-When I did that a few years ago, I was using two LandStars on the one battery set, so the two controllers were identical. Worked great. Maybe get a second ViewStar instead of the Bogart?
