The Raptor Sleep-Shelter is different. It's a modular system that has refined capabilities and functionality. It is not designed to be like a Swiss Army Knife in nature. Quite the contrary...It is up to the user to select the panels or modules they need or want. The Raptor is not a ready made system. I painstakingly designed all of the panels and modules to work in concert with each other, when and if they are attached. Therefore, they are specialized in their ability to perform with a higher degree of efficiency.
Hope that helps and thanks again for your input.
