Most of the guys posting here (including myself) are running big newer diesel pushers, with multiple thousand watt builtin inverters, even several all electric coaches. We have lots of batteries.
Your 1 chassis and 2 coach batteries on an older gasser will be plenty for your coach, unless you've added a lot of electrical loads, or spend a lot of time boondocking and prefer not to run your genny.
One thing always worth doing is adding a system to charge both battery banks off any available power source, shore, genny, or engine alternator. This will help ensure your batteries are all kept charged as much as possible. Such a setup will also ensure that inverter powered entertainment systems will not drain the house batteries will driving down the road.
