What battery do I recommend? Either. Follow my questions, above, to help make your decision. Me? I would, and will, keep using 6v batteries. Now if someone would GIVE me $4,000 I would switch to AGM batteries, over FWC batteries, as it was a price point for me, but they would still be 6v.

Yes, having 5 pairs of 6Vs will abate any concern over a single 6V failure!
1160AH and 600W of solar, wow! No wonder you have a cargo trailer.
Your $ figures are way off. Based on today's prices, 6V FLA GCs are $109. AGM grp 31s and 6Vs are $170 at club stores. (170-109)/109 = 56%. The price premium for AGMs is 56%. 10 x $109 = $1090 for new GCs. $1090 * 156% = $1700 and a difference of $610 for AGMs.
Of course you will only get 1000AH from the AGMs.
Deka specs. Note that there is no advantage for 2 x GC AGMs compared to 2 x 31s for total AHs. The 31s give more AHs.
