I had previously uploaded part 3 but somehow it was all black. So here is the new rendition of RV rear wall rebuild part 3. Unfortunately I can’t find the video where I was installing all of my insulation. But, I used the 1” or 1.5” foam board insulation. This is more like a combination of video 3 and video 4. Take a look at my thumbnail and you will know what I’m talking about. Comment below any questions or what you’ve experienced. Thanks for watching! Enjoy!
