I'm wondering if it would be better to mount both batteries on the tongue and wire them together in parallel, or use one by itself, then use the second one. The batteries would never be connected together in this scenario. [b]Anyone have any experiences or expertise on this?

My experience is a little different than yours, but I thought I'd share it here.
In my 16'
Fiber Stream, I have added several features that require AC power. I also evenly split my camping time between "
hook-up" sites and "
boondock" sites.
When "
boondocking" I have learned to forget the Air Conditioner,
Microwave Oven, and the Automatic Drip Coffee-maker.
But, when camping during
what passes for winter in Southern California, it mainly gets dark early, and I wanted to use my TV/VCR and my CD player in "
boondock" sites. For that, I have a 300 watt inverter.
However, I have experienced battery failure during a camping trip.
In my situation, loss of power to the water pump is even more critical than loss of
lighting or loss of heater blower-motor function.
I do not want to jeopardize vital housekeeping functions by draining the house battery while watching a video.
For this reason, I have 2 group 27 batteries, installed separately. My house battery runs the
lights, water pump, and heater blower-motor, as the trailer was origionally designed.
My separate
portable battery feeds the 300 watt inverter, mounted under the streetside bunk, with a DC power cord that feeds through the AC power cord hatch.
It is also available as a back-up to the house battery.
