I was wondering how the inside moisture is controlled under the shrink
wrap? Is there a provision for some means of insulation? I'd think
that condensation would build on the inside, somewhere.

In the early days of shrink wrapping a number of boats were ruined by
mold and mildew because they forgot to allow for ventilation. It's
really important to have dry bilges also.

You get a lot of solar heating and light under the wrap however and it
can be quite pleasant working on projects during the winter as long as
the sun is out.
