I feel that this is somewhat of a lost cause, but I have to ask... I would love to add some type of roll bar or light bar onto the bed of my '04 Silverado, but the problem is that I have a roll-up tonneau cover that I'm not willing to part with. It only goes to the inside of the bed rails, so the rails and stake pockets are still exposed. So I'm really looking for a chrome tube roll bar (that matches the OEM Chevy Step rail tubes) that mounts onto the bed rails. It's truly just for looks, but maybe I'd add some lights onto it down the road. I've done a bit of searching for them but have come up empty. Any suggestions??
