I don't know about 2012 but on my 2016, everything seems to be using screws and should come apart. And importantly, the vinyl flooring goes all the way under the cabinets. The internal panels are also of the same type, i.e. finished, than the outside ones. So other than screw holes, you may be able to take it apart and have it be OK.
If you can, stick your head in there and see if you can locate the screws and verify that the floor is finished and such.
I am also a boat guy and do find a lot of similarities here. The experience is far better than boating though as the thing does not rock or slosh when you are sleeping.
