Anyone done this? Can you add them?

The overhead rail system was the reason I put off getting a F150. The 1st time I went to the lot every truck had that and it made me want to throw up.

 

I'm sure people have tried...(not being smart but) you might want to search for it.

I like them but the lack of accessories has really let me down. It was worth it for the DVD but other than that at this point I'd have taken the sunroof.
