The ProSeries 15k is what they call a slide bar jaw design. As some have alluded to the more premium hitches use wrap around Jaws. Either a single claw jaw or a double claw jaw.
It is worth noting that for years people swore by slide bar jaw hitches because of how secure they are. Basically if the bar is across he pin there is no way for the hitch to let go of the kingpin.
The problem comes when it's time to unhitch. The ProSeries 15k is not a true 4 way articulating hitch. It's a 2- way articulating hitch with a plate that can pivot side to side. Note that the slide bar does not pivot side to side just the top plate.
If your camper and truck is unlevel when you try to unhitch you can find your king pin and slide bar in a bind...meaning that's it time to break out the mallet. Some have mitigated this by slightly backing into the kingpin when they get the camper positioned, setting the parking break, and then unhitch. This relieves the pressure on the slide bar and can make it easier to unhitch. Or they have resorted to leveling the truck with boards to relieve the bind.
Many in a position you are in have simply watched Craigslist or visited some Mom&Pop RV stores and bought a used fifth wheel hitch. The Reese dual jaw hitch with 4 way articulation is a great hitch. You can service them easily as Reese makes replacement springs and jaws if you need them. You should be able to find one for well under $300.00. The latching handle on these 16k Reese hitches has a strange upward bend in them and some kingpin boxes hit them depending on how they are designed. A hacksaw and a drill bit fixes this problem.
The ProSeries 15k is a strong hitch and it has great reviews on etrailer. Many are happy with it. If you go with this hitch just learn the ins and outs of using it and enjoy camping.
Thanks!
