Tents with vestibule

 

— the tambour is the extra space inside the tent between the main living area and the exit to the outside. It is found both in two-layer (between the outer and inner tent), and in single-layer models; most often does not have its own bottom, although there are exceptions. The tambour can be used for storing things, organizing an extra bed, and if size permits, for arranging a kitchen or dining room, etc.
