It is very likely that the manufacturers design almost all 6 volt
batteries to withstand more abuse like 100% discharge, temperature
extremes and vibration. However if you get a 12 volt battery from the
same manufacturer, built to the same design spec and use it in the
same application, the 12 volt system will last longer and outperform
the 6 volt with less maintenance.

Really? Do you have a reference for a 100AH battery made to Group 22 size?
9-3/8x5-1/2x9-1/4, by far the most common cheap battery put in a cheap car.
While you're at it, please reconcile your statement that 2 55AH batteries will
be better than a single 100AH battery, when extra connections are such a bad
thing.

Jack, 'battery systems' in Santee has blems some times at half
price, full warrenty. great customerservice.
http://batterysystems.net/locations/location.php?state=CA&id=28
the big box stores sell "marine starting", "marine/rv" and "rv"
batteries. the marine starting are not deepcycle.
Unless you can 'series connect' a pair of 6V, you may have to stay
with 12Volt batteries. It seems safe to go with Trogen brand.
how is the possum?

Nope that's a pretty small case, but there are 55ah batteries in
larger cases that share cases with 100ah batteries.

IF and on IF one 55ah battery will still crank you over, you have 100%
redundancy. Any of the extra connections can fail and you can still get
home. One connection fails on the 100ah setup and you're walking.

Years ago, I worked for a college and had CERTIFICATION authority to
confer degrees at graduation.
I no longer have that authority as I am now just another "honest"
run of the mill attorney at law retired in my
wanderlodge "contibuting," on occasion to this Forum.
However, after reading most recent comments, awarding a degree
of "ditchdigger" would seem appropriate as one continues to "dig" a
deep hole..

Hank, "Ditch digger" is not an honorary degree. and Honest attorneys
are not "run of the mill". "Contributing" require the skin to admit
you erred and learned your assumptions were untrue.
I dont think the hippie will learn. Some folks need GPS to find
their way home.

I can't help but comment on this one.
Old and new batteries mixed would most likely have eddy currents flowing between the batteries due to deterioration of th internal currents and would definitely have reducing effect on the AH and therefore the cranking amps too.
There are good points on both sides of this discussion. No need to beat each other up.
Oh by the way my qualifications are over 30 years experience electronics with an engineering background. Not a graduate engineer but definitely schooled in several good engineering schools. In summary I was a practical applications electronic tech.
Just my two cents.

Don't you just love this Forum!!!
We all get a chance to "share" our inputs and others keep our feet to
the fire if we get a bit off the mark as we have witnessed on
this "COACH BATTERIS" subject. Maybe it is time to shut this topic
down as we have probably learned enough.
I would appreciate more SOLAR panel input from members before I buy a
panel or two for my bird roof. I liked unisolar 64 but that is
seven years ago technology. Any new stuff out there???? Thanks.
