I know this is an old post but I couldn't find any pics either, so I went out to the dealership and bought one 2day ($75CAD), installed it (didn't like the drilling part) here's the endpics...

 

The reason it comes on the 1500 is they display the MPG #'s on the lot and this thing is supposed to help smooth the air coming of the back end of the truck netting a 1/2 or more MPG. GM did a bunch of wind tunnel tests and found it to help I guess DC followed and Ford may be next. It is blingy but supposed to actually help. The reason it ain't on the 2500+ trucks is they dont display the MPG's on the lot. So they skip it...

 

I like it, can you stand on it?

Sometimes my truck is so loaded with tools and junk that I can't stand anywhere but the bed rails or the tailgate to find anything.


Looks good ...................Jim
