Going off grid isn't something one does lightly.
Which was my point :). You seemed to be suggesting you could just buy 2x $3500 batteries and go completely off the grid.
To quote from the original post:
"Solar panels are cheap enough you only need batteries to last one night, as you can size the array to operate your loads even on cloudy days."

But they could now, and most deep cycle lead acid batteries are flooded, not sealed, which means they have to be ventilated to prevent hydrogen explosions hazards. Not so with Tesla's offering.
Fine. 4.8kW Li-Ion battery for USD$3,278 1.9kW for USD$1,678. My point is that Tesla isn't really doing anything really unique here. Sure, they're giving it more press than anyone really has before, but the products aren't especially cheap, innovative or special. http://ironedison.com/12-volt-lithium-battery-for-solar
How well do you think these would work in RVs when paired with the number of solar panels that fit on top of an RV? Would this work well at burning man vs running a generator?
TL;DR you're better off going in on that industrial diesel 3-phase generator rental which comes on its own trailer.

I feel like a backup generator is the last place where I would make my decisions based on the environment. I mean how long is it actually going to be active? Also batteries aren't exactly environment friendly either.
That may well be how you feel, but lately I feel like any burning of petrol is just disgusting (though I still do it as I cannot afford alternatives at the moment). I want to completely divest from fossil fuels, even for intermittent use. That's as much for the social value of saying "yeah I don't use fossil fuels and it's great" as it is for the environmental impact. I want to try all this tech to be an early adopte…

Less storage than a Nomad.
I'm going to install a 9kW solar grid on my roof in the next couple of months - capital cost is ~$40K USD. Without the Power Wall, I'd be selling power back to the utility at around $0.10 / kWh, and buying it back at $0.09 / kWh in the evenings. The Power Wall will also let me endure grid outages as well (you can't run your house on your solar panels directly). I'm really curious about what the end-user cost is going…
That's crazy expensive. My parents just installed 5kW last month in Australia for $10k AUD (and the government rebated them $5k AUD) so their out-of-pocket was $5k, or $1k / kW, fully installed, including the inverter.
Wow This thing could sell like crazy in places like India. 10 kwH is enough to power an Indian home for more than a day and at 3500 dollars most middle class people would consider buying it seeing how frequent power cuts here are.
Really? According to wiki, India's middle-class makes anywhere from $10 to $50 per day. When you factor in that this will cost a lot more than $3500, would these really sell like crazy?
So why not solar power (1kW), storage (3.6kWh) with 25+ year life, inverter (2.8kW) and other electrical systems for just USD$8,702. The batteries are only USD$2,910 of that. http://ironedison.com/edison-power-plus-system

What if one has already dozens of photovoltaic solar panels, and just need a good energy storage solution that lasts many years? I trust Tesla more than some others companies that they can deliver it.
You shouldn't. Tesla have a much shorter track record than someone like Iron Edison. Also… if you read my comment, you'll see the batteries are cheaper than Tesla's… and if you look online, you can see they come in various configurations… rather than predefined 10kWh bricks with 2kW output.
Why?
No, I don't want to hear what you're already thinking about typing. I want you to ask yourself why. I don't actually care (you're some stranger, we'll probably never talk again) -- but you should.
