Choice of Batteries - Which Would You Choose?

How about a couple of these Fullriver models, in either 6V or 12V type:

(I installed two Fullriver 115 AH 12V AGM models in our RV this past summer, at a little over $300 each.)
How are those performing?

They're doing great so far, but I've only RV'd around 11,000 miles with them since I bought them last summer. Providing a total of 230 AH of AGM capacity, they of course easily ran the furnace and many other things as much as we needed for 2-3 days before recharge. The engine alternator and stock 45 amp converter seem to take care of them fine - just like the situation with my last set of 12V Interstate wheelchair AGM batteries for about 8 years.

I chose Fullriver AGM batteries over Rolls-Surrette and Lifeline AGM batteries for these two reasons:

1) I have great respect for Rolls-Surrette batteries and I found out that Rolls-Surrette did not yet themselves make their AGM battery model I wanted .... Fullriver made it for them and relabeled the model for Rolls-Surrette. I bought the equivalent Fullriver model since there was a local distributor for it.

2) A Lifeline technical spec was not right for me (in print ... and confirmed by my phone call to Lifeline). I wanted 12V AGM batteries with a float spec range of 13.5 to 13.8 volts for a perfect match to my Parallax 45 amp converter, as the batteries would be on the converter 24/7 whenever the RV is sitting in the back yard between trips. Lifeline wants users to float their 12V AGM batteries within a lower voltage range so as to not "dry them out" (as the Lifeline person on the phone described it). I bought the Fullriver batteries instead ... they were only slightly less expensive than the Lifelines - so cost was not a factor.
