B&W RVK3300. It's rated for 15,000k, the next one up is quite a bit more expensive, and rated for 20,000K. However, the camper is nowhere near that weight.
Yes, you are correct, the camper is slightly nose high in the picture. This was my first experience with the truck, the hitch, and the camper. The hitch does have some adjustability front back, and in its height. The picture I posted is straight from the dealer, where we picked up the camper. I had the hitch position at the setting closest to the tailgate, and right in the middle in terms of its height adjustment. Once I unhooked the camper, I did drop the hitch down to its lowest setting. It's very very close to level now, and pulls great. Just make sure you double check the height between the bed rail and your camper. Usually no less than 6 inches is recommended, but that opinion can vary.
As a side note, the camper comes with what's called a Turning Point kingpin/hitch box. There was a lot of debate online as to whether or not you could take advantage of the turning point with a B&W hitch. And the answer is yes. The fifth wheel specialist at the dealership will need to remove a few bolts, and move the "wedge" forward, all while hooked up to the truck. It's not difficult, but does take some patience. Once the wedge is securely moved forward the rotating point now moves back to the trailer hitch box, and not your fifth wheel hitch itself. I was able to back the trailer up a full 90°, at the dealership before I left, to make sure I did not mash my cab. It does make backing up a little bit more challenging, but nothing that cannot be addressed with some practice. Hope this helped, good luck.
