I put a Roof nest on top of my Chevy. Seems to be pretty good quality material, and built well. Takes 30 seconds to pop it up, about 2 mins to take it down. I keep all my pillows and bedding in it while collapsed and no leaks yet. I went with the largest one they had because of the head room...
Us cargo control made it for me. I just gave them my dimensions. It was cheaper to install this than the OME headliner and it's functionable now. I'm working on putting in some Xmat heat/sound deadener, then I'll just store blankets and cold gear up in it.
After over a 100 man hours, I finally got the rusted piggy primed inside and out and raptor lined. I severely underestimated the amount of work this was. Looking forward to other projects not involving a welder, grinder, and sheet metal.
