An RDT is the best way to go all around. Basically crank case fumes were intended to be vented to atmosphere since the dawn of internal combustion. It's only the emissions requirements that have forced manufactures to adopt systems that range from simple to elaborate, many prone to failure and creating excessive cost. If you can get away with one, there is nothing better. I have one on all 3 of my rigs, and yes they vent fumes and noticeable vapor. I sit in bumper to bumper traffic every day with the Moosestang breathing on peoples little foreign cars like an angry draggon. It's highly satisfying to see some arogant SOB who changes lanes without a turn signal like he owns the highway in his BMW sit surrounded by a cloud of vapor that comes from such a lowly dreg of society such as I. Oh, he may not know where it's coming from, but I do. 
It's guys like him who passed the laws requiring crankcase recirculation to start with. All part of their overall desire to control everybody else while doing whatever the hell they want to on their own. Hmmmm... seems two can play that game. An no, I rarely smell it myself, and the vent tube comes out near the steering box.
