Hmmm. I don't use AGM's for chassis batteries. The last two I bought from Sam's Club were around 200.

I don't worry about the cross charging issues of mixing two different battery types since I have my coach setup that I only charge the house batteries from the alternator IF I use the merge switch.

AGM's work as chassis batteries but they are not designed specifically to work best in that use. Plain old lead acid's are the best for the high current rapid discharge that occurs during cranking.



Just my opinion.

The agms from O'rilleys are start batteries that are built heavy enough that they make good house batteries also.
If you have been to any auto parts store lately, you will find many manufacturers are now making agm start batteries with the same specs as regular wet cell batteries. 
Foretravel has been using agm start batteries in their coaches for 25 years.
The charging parameters of agm and wet cell batteries are close enough, that separate charging voltages are not required.

My opinion also.
