I have the CX on my truck (2010 FX4). Happy with it so far. It's also less expensive.

 

Can anyone help me out? I think my Cap is a A.R.E. z series but there are no decals and I just recently purchased the truck. Once I figure out whether it is that or a Leer 100R, I'm probably going to sell it. Thanks for the help!

 

I finally got around to buying the Z series cap. Got the drop down slider window in the front. Looks good.
