Thanks guys.
I ordered a hitch today from a local truck accessory place that I've done business with for years. Its a Curt 16K lb standard 5th wheel hitch. The head pivots front back and side to side, and it has a two jaw locking mechanism. Pretty sure it'll get the job done. I was looking at getting the B&W turnover ball and the companion 5th wheel hitch, but that would have doubled the cost. I also opted to have them install the hitch as I'm in a time crunch.
What say you guys about lube on the king pin? I'm getting one of those plastic plates to go between the hitch and the pinbox, but what about lube on the king pin itself?
