I would like to see confirmation that the Thor/Mastervolt system uses Lithium Iron Phosphate battery chemistry as expected, but assuming it does, battery cost should be well under $1,000 per 100 Ah of capacity. And if it uses 800 Ah, then cost for battery should be less than $8,000.
If we assume deletion of Onan generator and traditional AGM house batteries saves enough to pay for larger-capacity inverter/charger (should be plenty), then cost of alternator is only other major component. For now that alternator has to be aftermarket, I’d guess a cost adder for total system of ~ $10,000 should be enough based on present retail prices.
Once chassis manufacturers like Ford start to offer 2nd alternators for well under $1,000 (in a few months), and lithium batteries are purchased in volume, cost should drop to < $5,000, particularly if battery capacity is kept around 7.8 kWh like on Travato (~600 Ah at 13.2 Volts).
I like where this seems to be headed.
