NC, I don't think the weight of the hitch itself factors into it's own rating.
The dry hitch weight of your rig is listed as 870 lbs by Jayco...you really added a lot of weight up front. Is there any way to re-distribute weight and pack some some stuff behind the axles of the TT? Maybe store some lighter stuff under the front bed and move some heavier items to the rear?
I extended the frame of our TT and added a storage box for the Honda 2000 and some other stuff:

The good news is that both of these hitches are indifferent to tongue weight...in other words a heavy tongue is not needed to manage sway, the hitch uses the 4-bar linkage to keep the TT from swaying. The hitch won't allow the TT to sway regardless of how light the tongue is.
There have been a few reported issues of a busted Hensley...one was from member carringb who blew his up towing a very heavy toy hauler with his van. When I say blew it up, it broke in half IIRC....here's the
thread here on the forum discussing this about a year ago.
My HA is only rated for 1200 lbs, they didn't certify it for a higher weight and make 1400 lb bars available till a few years after I got mine (mine is a 2002). Last time I calculated my tongue weight it was about 1200 lbs and I'm running 1200 lb bars on mine.
The HA is designed with a bronze bushing in the hitch head where the spring bars insert. This bushing wears over time, and the closer to the limit you run, the faster it wears. I'm on my 3rd one right now. When it wears, the spring bar holes elongate and you have to crank the bars up more to get the same level of weight distribution. The good news is that this sacrificial bushing is easy to change and prevents damage to the hitch itself. I'm not sure if the PP has the same (or maybe a better) design.
Off the top of my head I don't think that you would have issues running either hitch at your current tongue weight...but since the heavy tongue is what's causing the ride issues in the truck, I would look for ways to lighten the tongue. As I said, either hitch does not allow the TT to sway regardless of how light the tongue is.
On edit, I found the
thread on the wear bushings.
