I have been talking with All-Pro in the hopes that they make something similar for the 2nd Gen trucks. I would love to run a rack system like freeze but I need the flexibility to pull it out at anytime or shorten it. Freezes rack bolts into the bed via the bed bolts, and can only be removed by removing the bolts. There is another guy in the club that has the same rack but has a quick release system that lets him pull it out so he can fit in his sled. What I want is a rack that can hold gear, can be broken down when needed and can be stored in parts in the bed, or in a small storage box.
If your going to take a crack at building one of these, I might have to make a trip down to Texas and get one off you!
