Yes it is designed to be used with the larger shelters as well.
Skunkworks alert:
Here is a proto, with a tarp vestibule attached. This is NOT a waterproof configuration. It is a DWR fabric on the nest, and waterproof vestibule. The vestibule , does not close up totally tight to the nest, however, this should in many instances, provide a lot of weather resistance. I was curious, if it would work well to cover the front, and it does work reasonably well.
