Today I cleaned the outside of our Airstream. Yesterday was all about the inside, today was all about the outside. I started from the top and worked my way down.
While I was tending to the detailing, Sean doubled our stored power by changing out the lead acid batteries with lithium ion batteries.

We should have the ability to go five to seven days on battery alone for basic needs (lighting, fridge low volt system, inverter to charge computers, and television).
