Hi, I'm brand new to this forum and just started my build today. I'm generally following George Coe's "Bug Out" build, but plan to put this in my pickup bed, so the door has to go in the back. (I know, that big box is going to look funky in the back of my pickup, but oh well.)
My main question is about the foam: I could only find 2" foam sheets that are "scored" to make them break easily at 16, 24, and 32 inches widths. The scores are about 1/2" deep through both faces of the sheets. I read a lot of messages on the forum, but couldn't find this question addressed directly. My guess is that the foam isn't providing any real strength to the walls, it's the canvas and TB2 that provide the strength. So should I do anything like put glue in the scores, or just let them be? If I should glue them, what's the best glue to use?
Also, because I don't want to bolt through my pickup bed, I'm planning to build a 2x2 frame inside the foam box, supporting 2x2 rafters that will go through the foam at the top of the walls, and which will anchor a 2x4 rail on the outside, flush with the roof. I'll canvas over those rails, and mount D rings for ratchet straps to my anchor points in the pickup bed rails. I'm thinking this should provide enough structure to secure it to the pickup. The outside wood rails will also provide a good anchor for awnings. Sound reasonable?
Thanks for any feedback anyone can give.
