I took a couple of pics of a friends off grid home system today where he successfully used harvested battery modules from a Tesla car. He really knows what he is doing and did it right including active electronic battery management and automatic active liquid heating and cooling utilizing the Tesla battery module fluid loops. I tried to up load two pics to the GMC Photos site but kept getting an error creating re-sized original, error code 1 message. One shows his installation and the other is a pic of the Tesla data collection PC card that feeds info to the car computer and passes control signals back to the various components to keep the batteries safe and alive. If anyone is interested, drop me an email and I will forward them to you.
My concern with our owners trying to harvest batteries from e-cars is that those battery banks internally can expose one to a few hundred volts DC which is enough to severely damage or even kill an unsuspecting person. I shutter when i see things like the stupid Utube video of a person trying to hack into a sealed Leaf battery pack with pry bars, hammers and a recip saw. If you really know what you are doing you can utilize modules of these cells, like my friend here did, but the management of even those cell modules is critical to safety. Before you attempt using these, do a lot of reading on the risks inherent in lithium-cobalt-aluminum battery chemistry and what it takes to use batteries of that type safely.

Jerry and others, be patient, "second life" batteries are coming. I've been fortunate enough to help some public agency to get 18 electric buses (proterra) into their fleet, including up to 1000V 125kW charging. I also attended EV training. The Proterra batteries, like others have a limited life as a primary drive battery, after 3-4 years they need to be replaced to maintain the high demand discharge. however these old batteries known as "second life" batteries are perfect for stationary storage for backup load response applications, and yes RVs. You'll just need to get the correct charge controller.
Although there will be a market for these batteries soon, they will include hybrid, plug in electric and all electric cars and buses. There are some brokers and distributors popping up. I'll keep you posted.
Respectfully,
Sean
