Looking for Tonneau Recommendation

I would like to put a tonneau cover on my 2010 DCSB. Preferably a roll up, but that's not set in stone.
Are there any that allow full use of the factory bed rails? I use my rails a lot and would hate to have limited or no use of them.
I'd love to hear any recommendations. I did a search, but either my search skills suck or I came up empty with regards to my wants.
Thanks in advance.

 

I believe I found a very useful thread. Thanks anyways.

 

You are welcome.

 

I got a tonneau pro tri fold on autoanything. They have roll up aswell and for the price you cant beat it

 

If you're wanting to go with a soft roll up that allows you to use your factory track system, I would recommend something like the TruXedo TruXport. Well built cover, high quality vinyl and does a great job at keeping water out of the bed. Access makes some great options as well that will fully accommodate your rail system!

Good luck!
