Ok, My build on turning the back of my truck into a camper at night/dead animal carrier by day is going through next weekend. One Problem, my camper shell isn't carpeted and I would like it to be. $1400 is out of the question for a new one (even though I do want a gun rack in it).

So.

Indoor/Outdoor Carpet - Where do I find it? Menards? We don't have one close by so I can't just run out and look.

Attaching it, whats the best way to attach it? Spray adhesion, Silicone.

And is there any trick to getting it to wrap around my windows nice?

 

menards for the carpet dunno about attaching it

 

Get ya some of that astro turf instead of carpet.

 

I believe what they put in there is more like a felt, not carpet backing. The 'carpet' in my leer went behind the window frames, like they covered all of the fiberglass, cut open the size of the window and put the window frame on top of the carpet.
Maybe it is possible to fiberglass in a few blocks of wood (2x4 or something) before carpeting, that way you can screw a gun rack, or whatever you want, to it.
