9.6 Bigfoot Dual Batteries
I am looking for 2 AGM batteries that will fit into my 2001 9.6 Bigfoot truck camper. I want them to fit in the stock location but most AGM's are pretty big. What is everyone using? Maybe I should jus...

Would you reccomend it over an on board charger/inveter?
What would be reason for extended high voltage?
Though batteries seems to be a moving target Ops intent was 2 or 3 AGMs. In your opinion or information you based your decision on would it be more beneficial for Bigfeets intent and usage?

I am having surgery today and will be out of pocket for the next few days. I understand the OP want as little maintenance effort as possible. I feel the same way as I have been 100% AGM since 2009.
The voltage is not extended, it is necessary until float. The converter/charger is primarily a power supply and that is why it is so quick to fall back to 13.6V.
Temperature compensation is very helpful as it adjusts the charging Volts according to the battery temperature. This is a key factor in unattended charging. Read the specs for the Xantrex Truecharge2. I don't have one but it will give you a good idea of what I would trust to leave unattended on my AGMs.
The portable charger measures its own temp, so it needs be placed so it can know the battery temp if left unattended.
I trust my two solar controllers to run unattended year round. The typical converter/charger is no where near as smart. I don't leave my WFCO unattended. Details of my systems are in my profile.
