I have to agree with this. The concept is sound for sure, but all.. that.. wood... He's adding so much extra weight (and thus lowering his average mpg etc.), when a type of plastic (the slightly bendy stuff that cooking/food storage tubs are made of) would have been good enough, and also much lighter. The drawers under the bed especially - those in my opinion should be either wireframe and canvas, or based around prebuilt plastic storage.
I also think he wasted space above the bed - there could be wall nets for smaller items, or even a drop down surface for cooking or day work.
Finally, he's assumed that the wiring will never fail or need updating - it's all now trapped behind the (many layers of) flooring or the wall panels. One fried cable, and he'll have to rip out all that 'nice' cabinet work.
I love the idea of kitting out a van and going mobile, but that interior is NOT how I'd do it.
-As one who has toyed enough with the idea (not to live in permanently, but for overlanding) to start kitting out a Land Cruiser 78 to make it liveable, I'd agree with most of your points - though presumably, if he mostly sticks to highways or at the very least properly paved roads, mpg shouldn't suffer too much from a couple of hundred pounds of additional weight.
My one MAJOR gripe with his build, is the water jerry can directly behind the driver's seat - in the event of a crash, he is -quite literally- trusting his life to the straps securing the can. I wouldn't do that. Definitely at the very least have a proper base for the can to sit in, rather than relying on straps.
Edit: Oh, and I hope there's proper ventilation from the cupboard where he stores the cooking gas. One leaky can and you're in for a potentially very nasty surprise. (I solved this the lazy way - by using a kerosene stove...) /edit
Hopefully, the sink and countertop are secured well enough to the van not to come flying forward, too.
That aside, I have nothing but admiration for people with the chutzpah to actually go ahead and DO what they dream of. I wish him many a happy year on the road.
