I know Parts&Service mentioned this a while back but this one is supose to be solid black steel. It is from a local Dodge dealer that sells parts online. Check it out.............

Looks just like the ones that came stock in my truck, if there's any steel in there then it's paper thin.

 

Those ones are like what my brother had in his 06 1500 and there wasn't very much metal in them at all as far as we could tell. They looked and felt like it was just a fabric covered piece of plastic. The ones I have in my 03 2500 are actual metal that are not fabric covered. I will try to get a picture of them and post it today for you.

The nice thing about the ones you listed are that they are covered in fabric so if you have a dog in the back it wont slip all over the place where as the full metal ones aren't covered and they are corrugated and not a flat serface.

Just did a quick search and found a picture of the ones I have.

 

It looks like a mismatch between the description and the image. Old description / newer picture.

 

I am going to order one on Monday and check it out, Will let you guys know whats up with it. And I can get you a better deal.

 

Get me a hell of a deal on that 2006 Suzuki M109R You guys have on the show room floor.

 

They just sold that... It was a great bike. I helped the guy load it to take to somewhere up north......
