Jungle is one of the more camping friendly maps. I got my first 30-0 area camping very much like this before.
In this video i go for 30-2. You can also area camp on various other parts of the map. Basically it's one of those maps made for campers.
This video basically shows why Jungle, along Sewers and Docks, if i put them in a map ranking order would find itself among the bottom.
