You just take out all the screws - four on each hinge and two under the coin holders at the windshield end and it lifts right out. In my 2016, the hole was cut except for four little tabs that I had to cut with a small saw. Take out the screws at the hinges carefully and slowly with a power drill. They are in there solid and you can easily strip them - if you are not careful and deliberate. Then take off the large air hoses, tie the other hoses off, disconnect the battery and lift it out. It is heavy and unwieldy and just fits - but it is doable. Two people is safer and easier - although only one can actually lift it out. Reinstalling it, I filled the whole area under the desk with insulation, made some tabs for the piece of wood I cut out and screwed it back on. Then lots of duct tape.
