Dual 6 volts, any thoughts or second opinions?
Probably due for new battery (batteries?) soon.
History:
Campground to campground.., every time, 50 amp plug-ins (Mama's choice), where available.
Only boondock overnight occasionally, while en-route.
Upon return home... plug in for maintenance, refrigeration, and storage ...
Stay plugged in for "WINTER REFUGE" (Nov thru Mar) in cases of Loss of power to residence. (I have a 10 foot Bargman 7 pin male to 7 pin ten female foot (8 gauge) extension for 12v charging if necessary, using Tow Vehicle as power source, also 975 watt generator for maintenance top off only charging, as back-ups).
Question(s):
1. Will dual 6'ers hold up better to constant 120v plug in "shore power" inverter charge, than a quality 12 Deep Cycle?
2. Isolate battery, and use Tender on 12v deep cycle battery while staying plugged in to "shore power" for general inverter use?
3. Any other advice, to maximize "Battery Life", and still maintain "at home flexibility"?

If you have not had any issues with your type of use with your current 12V deep cycle set-up, why fix what ain't broke? Were you a Nuke by chance?

If the vast majority of your camping involves 50A hookups, then I see no need for you to change to 2 6V batteries. For a night or two of dry camping, a single, well-maintained 12V battery will meet your needs.

I've seen 2 years out of a battery and I've seen 7 years. Want to know what condition they are in, charge them up, take 'em out, and find an Autozone to load test them.

1) I wouldn't assume that they'd do any better than any other flooded cell battery. How long they last on the chargers in my experience is usually related to how smart the chargers are. Chargers that change and hold to 14.7 are hard on batteries.
2) That's certainly a safer way to do it - they typically can't overcharge as easily.
3) For flooded cell, maintain the water level. With a new charger, I check to see what it's doing with a volt meter every now and then. My Jayco would hard charge to 14.7v and hold. Turns out there was a $20 module I could plug in and make the charger a lot *smarter*.
Generally what you get out of the 6V batteries is the ability to discharge deeper. You mention "deep cycle" by my understanding is that there are very few true deep cycle batteries out there (haven't done my homework in a while). Residential solar guys prefer the 6V stuff.

Unless you plan to boon-dock more than you indicated, I don't think they would be worth the weight or the cost.

Hey SEABEE, negatory on the NUKES... Airdale thru and thru! CVA42 "USS FDR", Aviation Electronics Tech, Radar, was my home. Went NUKE, as a civilian, post service at United Nuclear Corp. Montville, CT building fuel cells for the subs, ironically my office now has a slot machine. UNC went under, now the home of Mohegan Sun Tribal Casino... second largest Casino in the world. Foxwoods, then Mohegan Sun, both within 5 miles of each other.
Thanks for all of the input... concern is "unintended incidental Boondock winter camping" induced by shelter in place BLIZZARDS! (Global warming my behind! Last winter was cold!)

For the occasional overnight boon dock, the 6volts are overkill and any benefit from them does not compensate for the extra size and expense.
Another thing that many do not think about is that to get 12V you have to combine them in series. With a two battery setup, if you lose one of the batteries, nothing on your trailer works as you are down to a single 6V battery. A single properly charged 12V battery, properly charged will meet all of your needs.
