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.
