Your situation sounds so much like what I experienced a year ago. I went from a 25' trailer to a 34' trailer V-nose (very unstable design) and almost quit camping altogether, because of the sway.
I installed the Hensley on my own (as most people do)and have been extremely thrilled with it since. It's pretty straight-forward. The manual has pretty good step-by-step instructions. There are three different kinds of attachment brackets you'll be able to buy: The snap-up type, the hanging bracket, and the one which holds traditional tension adjusters. These three types are so the hitch can be used with a variety of trailers. The company will encourage you to get the adjustable type and I agree. I think they are easier to attach and you can make adjustments in how much tension is being put on the distribution bars. The other two types of brackets also work well.
You can get an online copy of the Hensley Arrow manual to look it over before you buy

Attaching the hitch (to the truck) takes a wee bit getting used to. I'm getting better at it. But there's a trick, and it's included in the back of the manual. Follow that and you won't go wrong.
The only concern I really had recently was when I dropped my trailer off at the RV dealership for service. I got with the forklift operator and showed him how it worked and how he was to move it. I watched him move the trailer into the back service yard with no problems, but when I went a week later to pick it up, a different operator had me drive back there to pick it up myself because he didn't want to fool with it.
They didn't damage it, thankfully, but I read them the pre-riot act of what would happen if they did. It is pretty sturdy and won't fall apart easily. I don't think it's any more delicate than the other hitches I have used. There's just more moving parts to it. :B
P.S.: From the looks of your new trailer (nice choice, I might add)it should be pretty easy to put the Hensley on it. Mine took a couple of days because of the faux diamond plate trim so near the tongue jack, but you shouldn't have that problem.
