In-channel is the way to go, IMO. Do a search. There's tons of info on this topic on here. I have the Wade vent visors and like them. About $45. Weathertech is also a forum favorite. They go for around $100. Ventshade and AVS also have styles available for Titans. A must have add-on for these trucks.
