On the other hand, if you’re going to include a generator anyway as a backup, then why spend so much on that much battery capacity? Granted, if the cost is indeed around $300 per kWh (or lower) as Jamie reports, then 36 kWh is under $11,000, so the high system cost is coming from somewhere else.
The difference between $125,000 for this lithium system seems out of proportion with what Winnebago charges, about $20,000, for the much smaller Travato system. And even that seems high to me.
Personally, I like the idea of having just enough batteries to boondock overnight, assuming you’re going to be driving next day to recharge. Initially that’s where I see the sweet spot between cost and capabilities, or most bang for the buck.

you hit a high point. it has an extra engine driven alternator to try to recharge. i could see a CG inquiring about how long to recharge, when you you have 100 amps of a/c power and over half that is just to run the equipment in the coach.
its a big battery bank and the earlier items on it suggested days of running the roof top a/c units. but at 125K i would stick with a 8k watt genny or 10k watt
