The way you put that it sounds like you are planning a second aux battery
under the back seat in parallel with an existing smaller battery already
under the drivers seat?  If so most wisdom regarding batteries says not to
parallel batteries that are not identical.  For my Norcold I have just one
aux battery, a Group 31 AGM, under the back seat.  The Norcold is wired
directly to the aux battery and so is an inverter and other stuff.  I have
not been aware of any problems with the Norcold because there are other
items running from the aux battery.
