Mixing AGM and Sealed Acid Batteries
We have a 2010 Jayco Seneca HD. The Chassis has two starting batteries and the House has 4 batteries. I am needing to replace all 6 batteries. I really want deep cycle AGM batteries for the House. ...

The answer is NO, you don't want to mix FLA with AGM.
Here is what has not been mentioned so far.
AGMs rest at 13V and FLAs rest at 12.65. If you leave them connected in parallel, the AGM will sacrifice Amps to keep the FLAs at 12.65. After some time, the Volts of the AGM will balance out to 12.65. At that point the AGM will be around 65% charged.
What is the correct charge Voltage?
What is the correct float Voltage?
I got my first AGM in 2009 and within one year went 100% AGM.

I still confidently say it is fine as proposed by the OP.
BTW this is a bit of a zombie thread. What did the OP do?
