I'm a total noob when it comes to hauling a trailer. I just got myself a 2016 Titan XD with the Cummins diesel. I have this idea that I can get a good sized toy hauler here in VA and drag it across the Rockies to CA. I spoke with someone that owns a newer XD and they said that I'd need the 5th wheel adapter Nissan P/N 999T5-W4198. This made sense as the 3 holes are officially supposed to be for a gooseneck. It dropped right into the 3 holes in the bed and looks great. Now I'm looking for a 5th wheel to mount on it. I dug around and found that Curt already makes a 5th wheel with "legs" that mount directly into the 3 holes in the bed. Does this mean I am officially an idiot for buying the adapter before checking into it more carefully? If not, what sort of 5th wheel will mount directly to the adapter?
