I like the colour scheme, materials and shape of the units, very classy. It's not minimalist though, that term seems to have been reduced to "it's got wood in it".
As above, the lack of workspace and huge hob and fixed tap suggests it's been made to be arty and appear in magazines rather than actually being used as a camper. And good luck keeping that matt black exterior looking good.
As a design exercise it works though just like the original California XXL concept, in that as a whole it doesn't work but everyone can take away one or two design elements that they'd like to use.
