Yes sorry, that was a slightly off-topic response.
Because it's hit-or-miss to bench test still-in-service batteries, in my research I found that specific batteries are only declared "exceptional" once they are something like 9 years old and still in service! And by then those particular batteries may not be produced anymore. In addition, in our case, there is a relatively small percentage of the trailer/RV population who use L16s. So specific experience is very limited, and you're on the right track by looking for general manufacturer feedback.
Trojan T-105's are written about all over the internet and well-respected. You'll find some write-ups with negative connotations after manufacturing location changes, but the brand is also generally well-respected.
Based anecdotally on the overwhelming number of solar installers and internet retailers I encountered who sell them, I'd guess that Lifeline batteries are right near the top of currently most commonly installed AGMs for RVs/Trailers. I haven't seen much negative on Lifeline. I haven't read any overwhelming praise either - but with batteries the saying: No News Is Good News probably applies.
I personally went with Crown primarily because of Handy Bob's relentless recommendation, and I knew from calling that the batteries were shipped direct from the factory (so I wouldn't get a set that had been sitting around for a year or two already).
I didn't read much positive about US Battery, and I'm entirely unfamiliar with Full River or Rolls-Surrette. Some on the internet say go with the cheap-o brand and maybe you'll get lucky with extended life. Other say 'quality' batteries are cheaper in "per year" prices. I don't know what is right.... and I don't think there is necessarily a right answer (at least, not until 10 years from now when you can use hindsight). Probably the best thing to do is google each of those brands until you've read enough to be comfortable with your own decision and price point.
