So I've got an old pride transport truck out of salt lake. It's really not insulated too well.
Like bare minimum.
Anyway, I bought some of this stuff and had the body shop install a bunch when they repaired the damage after the accident last January. You can really tell the difference on the back and left side of the sleeper compared to the right side.
I cut window pieces this week and put them in for the night.
Makes the truck much more bearable to sleep in now with just the apu and bunk heater running.
It's the same stuff that the windshield sun blocker is made out of.

Next project will be to wire the Arctic switch on the apu up so I can "turn on" the apu any time I want.
It will run for constantly then to keep the engine much warmer.
