I feel like it takes most people on the internet a weekend, maybe two, to finish their trailer insulation.
It's taken me... 4 months or so? Granted, insulation is near and dear to my heart and I consciously and happily went overboard on it, but I'm glad to be done with it.
Before I was able to put in the second layer of insulation I had to run all the wires that needed to go through the ceiling. Mostly lights, bathroom fan, an AC line, and the main cabin fan.
Then I laid 1" polyiso in between the furring strips, cutting out holes for the recessed lights.
Second layer of insulation going in
Second layer of insulation complete and taped.
I found some 1/2" styrofoam insulation (no, I don't like stryofoam, but nothing else I found worked and I like freezing my ass off less) and stuffed it up in the forward compound curve area and top sides.
A combination of careful cutting and fist-hammering got the awkward curve pieces in place.
Next I screwed 3/32" paneling to the furring strips, again cutting out for the lights and fans.
Halfway there
All cabin insulation is complete.
It feels really good to have this work done, and it's starting to halfway look like a habitable box.
Next step: the pine floor.
