Crewcab, I purchased a catch can at Tractor supply, around 10 bucks. Works great.
My hose only runs to the back of my cab.

I know a lot of you keep saying the the CCV has a very obnoxious odor. With my truck I don't find that to be the case. I had changed to Rotella Syn. before I did the CCv mod. Not sure if this has any effect on the odor.
