Rolled the trailer up on some ramps and took down the rear-most insulation sheet.
Well it practically fell down once I removed the bailing wire holding it up.
(While on a previous trip I noticed it hanging down) and bailing wire saved the day.
I had to go with 1" in this section due to a center brace in the way.
The rest is staying up fine but it'll get replaced with polyethylene soon. I can use 2" under the rest of the trailer.

Here's the damage the white insulation went through .
