Well.... I didn't use spray foam because of the permanence of it and
once you pull the trigger you are not going to be able to clean up the
potential of a horrific mess.
I did however line the entire interior with 3/4" cut and fit, foil lined
foam boards.
Foil was positioned in the 'up' position, pushing back at, and stopping
the UV from entering the trailer and touching anything in the interior.
The surface temps are way way down now. Interior temp meets the ambient
air temps of course, but not much more. The little mouse I found kick'n
it recently would probably agree too. Very inexpensive, it was a day
job, and if the next guy can't deal with the WTF fit and finish of it
all .... remove it all in a few hours.
Started out as an experiment, turned into another permanent
work-around/jury-rig. Did I mention cheeeeeeap ...

How did you attach the foam panels to the aluminum top?
