Insulating under bed in 171

So I sealed the edges of the plywood with silicone and took it out last weekend.  We had one cold night and I didn't feel any cold air blowing in from that area - much improved.  I was also sure to keep the storage doors closed tight.    I noticed some condensation along the seal between the roof and walls, so there's probably air leaking there as well.  Where else have people sealed their Pods?

The proper name for it is "radiant barrier".  Its best known by the trade name Reflectix.

I've noticed cold air getting sucked into the 171 between the plywood for the bed and the back wall which leads down to the storage area.   Make sure the storage doors are closed and consider a bead of silicone between the wall and plywood. You can add insulation after the airflow is stopped. I'm going to try this as well.

I would recommend picking up a roll of mylar/mirror/bubble wrap.  It is usually available in the building section of the big box stores.  It looks like bubble wrap but the plastic is coated with a mirror-like surface.  The bubbles act as thermal insulation and the mirrored surface reflects heat.
So it works great to keep hot sunlight out and reflects IR heat in the interior.  I cut it to fit the shape of my Pod's windows and use the blinds/curtains to keep it from falling out of the window frames.
I finally added a couple of industrial strength sticky-back Velcro to each sheet to help keep the panels from falling down.
The bubble sheets really work well...they stop most of the condensation/frost when nights get nippy.  My bed is located beneath the rear window and there is never any cold drafts when the sheets are installed.
I also use the inserts on the sunny side windows if I know that it is going to be a scorcher and I want to prevent the temp from building up too fast from sun shining through the windows.
