What is the smallest AC/cooler to cool down a small tent, assuming we will have access to the power grid? Really hoping for something that will fit in a 20L backpack...

Maybe something like this?

My wife and I (late 20s) are looking to join a camp! We don't drink, smoke or do drugs and would like to find like-minded people to enjoy Burning Man with! We will be coming from Washington DC. Ideal camp would provide electricity, 2-3 meals/day, shade, showers, and quiet hours so everyone gets a go...

Same here! Let me know if you got my message, we can share an RV and go together.
