Re: Charging both House and Start Batteries

I don't think you are missing anything.
It is up to you how you manage your batteries. If you want to treat your two battery banks as entirely separate systems, and only combine them in a (rare) emergency, then just keep doing what you are doing. You do have to take personal responsibility for keeping them both properly charged, but it sounds like you have that covered.
A few of our members have connected their chassis and coach battery banks permanently together into one big battery bank. This also works OK, as long as the operator is diligent about monitoring the SoC, and never lets the batteries get so depleted that they can't start either engine.
In short, if it works for you, then that is all that matters.
