Here's some info:

Not a lot of options for full length. I really wish FrontRunner would make one for the 3rd gen... only one missing from their site. K9's are pretty nice, but sit a little high for my liking. Gobi is super nice, but they are all $$$$$. Baja seems to be the best compromise, but I wish they made the utility rack for the 3rd gen as well. (like the 5th gen utility rack) as I'm not a fan of the side rails... all personal preference. but there's options, depends on what you're looking for and budget.
My personal favorite is @A.Wilson013 's. It's super simple and low profile, but solid at the same time. I'd like to make one like it at some point.
