The one thing I have really enjoyed about Camping 2.0 is the "mini-camp" system, where your background will often better suit the area you were in at the time of the long-rest. Helps so much with immersion. So much so, that I'd like to see it be the norm.....so that your long-rest background area will *always* match the location you were in when you took your long-rest. Just a thought.
Also, any chance you can have a minimum number of supplies needed to even manage a partial Long-rest?
