Hitch Advice

[Mikesr]

Recently took delivery on a Keystone Outback 325BH with a dry weight of 8400# and a hitch weight of 950# and is 37 feet long per manufacturer specs. TV is a 2005 Chevy Silverado 2500 HD 6.0 gas extended cab and 6.5 bed 4x4 with a 10.5 K tow rating.
Previously towed with an Equalizer hitch that had a 10 K Rating and 1000 lb bars. That TT was 7 K
With the purchase of the new TT we updated to a Blue Ox Sway Pro with 1500 Lb bars as per Dealer and Blue Ox recommendations. As mentioned in a previous post by me the TV had a light front end and some loss of steering above 55 MPH. Was advised to go up another link (to 10 links showing) on the Blue Ox, which is not possible. In order to get it to 9 links the back of the truck is EXTREMELY high and shows separation of the leaf springs just to hook and unhook the tension bars which are loaded with so much tension I feel unsafe trying to remove them.
Yesterday I spend ALL day with the dealer and they made a couple adjustments to the ball height of the Blue Ox and corrected some of the steering issues (not all) but this heavy load on the bars is still there and I feel unsafe to hitch and unhitch. I also placed 2 calls to Blue Ox to double check what the dealer was doing and they agreed and assured me the hitch was correct for the TT and TV at the specs given.
At the end of the day I came home with no camper. Frustrated and worried about my safety. The service manager was very helpful but my piece of mind was not satisfied.
He has now offered an even trade for installation of another WDH of my choice.
That's why I'm back here for advice.
The dealer stocks Reese Stait Line Dual Cam and Blue Ox.
He can order anything I want.
After looking over the Strait Line I'm leaning that way now. The bars look longer then Blue Ox and it looks much more adjustable (though not as simple as the Blue Ox)
As mentioned I liked the Equalizer I had but now need a12K with the 1200 # bars.
I know this is a long post but I trust you guys for some sound and safe advice.
Could my TV be undersized for this TT ? It tows it with no problems even on grades. Braking is great with my P3 controller. It's down to the weight distribution setup that will work for me.
I do understand I'm at the near the max of the truck but there is some margin. Could the overal age of the truck be a factor? Suspension is stock and original.
Thanks in advance for reading this and I welcome any and all advice.

I had a Hensley and loved it for it's "no sway" characteristics; however, I do not believe that the Pro Pride or Hensley has any special Weight distribution abilities over the other hitches mentioned. It's a lot of money spend, well worth it if you are trying to eliminate sway, but maybe not worth it if you are trying to improve weight distribution.

At 37ft and high dry weight...that's a monster bumper pull for any single rear wheel truck.

If your looking for absolutes, skip all the other WDH's and just take the plunge into a "premium level" WDH.

Just throwing this out... is the height of the unhitched trailer roughly the same as the truck? Maybe there is a height difference causing this? Could be changing the weight distribution somehow. Almost all hitches are adjustable for height.

My only contribution to your dilemma is to say that I loved my Equal-i-zer hitch when I used to tow TT's.

In my opinion, your truck is plenty stout enough for the job.
