I really don't know why it's one-night only. Maybe so it remains available for people like us to come in and spend a night and move on. I'm sure it would rapidly become like all others--always full, if they changed that rule. The how many nights question is there probably because they use the same envelopes everywhere.
The parking is like every other trail head--lots of cars for hikers far out in the back country. I've never checked bear boxes, etc. Seems really odd for people to leave stuff for months--Food doesn't last that long, and if it isn't food, why is it in a bear box?
