Very cool engineering and I'm sure they'll offer other modular packs to fit in that space. Couple things I noticed, the plastic/silicone expanding dish "sink" can be found (similar ones at least) off Amazon and I've used it camping for a while and its awesome.
Most importantly (to me), is that FOREST GREEN in the background?! It looks nice and truly green (less tan/brown).
That T slot system is really clever for taking the kitchen on and off. Hopefully it doesn't wear out over time. Also, the spot to be able to string up lights is a great touch too.
