6V vs. 12V Ah equal?
I am lucky in that my TC has a flexible space for batteries. Currently I have a group 27 interstate marine/Rv battery that I believe has around 100 amp hours (cant find a published number but remember...

There are a few differences.. As you opened your original post you said Group 27's were around 100 AH.. (Just under in my research) but then when you did your comparision suddenly you have 'em at 115 (Closer to a Group 29 rating)
And the GC-2's you rated 203 when they are usually 230.
Did you get your numbers crossed?
Next. The GC2 are DEEP CYCLE designed to be run down as low as 50 percent.
The Group 27 are most likely Marine/Deep cycle.. Lower internal resistance but.. They do not like to be run down so far.. say 75% soc minimum.
My old 12 volt was an interstate marine/rv with no AH listed (or that I could find on their site) so I was speculating on the AH's.
The original GC2's I was looking at were Costco batteries rated at 208 AH's. the GC2's I ended up buying were from SAMs club and were energizers by Johnson controls and are rated at 220AH.
So prior to the swap, my truck would charge the battery. After the swap, with deeply discharged batteries, for some reason the VSR isn't allowing charging.
