I just finished testing out a bike rack I made for the bed of my 2009 Silverado. The lip on the bed is only about 1/8" so I had to figure out a way to apply pressure from the lip to the main cross brace where I mounted two Delta Bike Hitch Pro fork mounting blocks. I can easily put another mount in the middle, maybe even two, but as it is, I can place each front tire between the rack and bed and pack the bed for camping. Here's a link to my photos. If guys are curious, I can go into more detail and take some more pictures. The mounts cost me a total of $32.90. The hardware was a few bucks for bolts, locking nuts and nylon washers. I used a couple of 2 x 4 pine studs I had handy, a couple of brass hinges I also had, used a bit of elbow grease on sanding, Thompson's Water Seal, and pieces of inner tube on the ends to add friction for a tight hold. However, the rubber needs replacing with something a little better.
