How do you plan to use your coach? Do you do much extended dry camping or just an occasional overnight?
The first step would be to determine your daily Amp Hour usage when dry camping. Victron BMV-712 battery monitor is great, and bluetooth. Their Smart Shunt is the same monitor without the display just bluetooth app on your phone or tablet. Once you determine how many amp hours you use then you'll know if 600 amp hours of LiFePO4 will be enough. Then comes the solar charging, ideally you'd like to have enough solar panels to fully recharge each day. There are various solar calculators online.
There are various ways to charge using the inverter/charger and your battery manufacturer will have the specs.
Also consider that if you plan to charge using your alternator while driving that the acceptance rate of the LiFePO4s could overheat your alternator. Victron Orion and Sterling both make a battery to battery charger that replaces your isolator and works well for different battery types.
Sounds like a nice project.
