Bed Extender

Hello all. New to the forum. Curious question:
Does Toyota (or anyone) make a bed extender that doesn't require drilling? I could've sworn I once saw a bed extender that used the factory bed trac rails as the attachment point and even allowed the extender to slide up and down the bed.

Any help, thanks

 

So all know. I did find the sliding bed extender that uses the trac system as it's connection point. It comes on the Nissan Frontier. I must've seen it during my truck shopping.
I think its a great idea and will do some investigating to see if the extender or its brackets can be used on the Tacoma
