So, I now leave the house batteries to "on" and the chassis batteries main to "off". I plug a trickle charger into an outlet (coach is plugged in for power all winter), and connect the charger to the chassis batteries directly after turning the master switch for the chassis batteries off.

I hope this explains it a little better. I've never been a wordsmith
You would think that FR would have wired so that all batteries house and chassis would have been charged by the battery charger.
Could that be why, when I start up that I get a "Low Voltage" indication on the FL instrument bar?. Seems like FR should come up with a way to do that without us having to put a separate trickle changer on the chassis batteries.

When you start your engine the low voltage indicator will come on because as Cummins has stated there is a heater in the intake to warm the air. It draws a lot of amps and pulls down the voltage from the chassis batteries. Perfectly normal. Try to increase the idle to speed up the process. The engine needs to get to about 100 degrees before the voltage will stabilize.
