I agree with TRBO's comments. I had a 32' lite fifth wheel with a conventional Reese fifth wheel hitch, and I absolutely hated that thing. On certain highways, the chucking felt like something was about to come apart. That 8000 lb trailer would jerk that 8000 lb truck around like a rag doll.
Recently made three significant changes;
1. bought a Silverback 29RE 12,000 lbs +/-
2. Had the dealer install a B&W turnover ball hitch
3. Had the dealer install a Reese Goosebox
The towing experience has been night and day, even with a heavier trailer. The Reese Goosebox incorporates the Fifth Airborne technology with an airbag and dual shocks. The airbag needs 50 psi. The pulling experience is so much softer and my chucking was reduced 90%. The occasional chucking is much softer and short lived.
The downside is that you have to keep an eye on the airbag pressure because each time you hit a pothole, the airbag pressure will spike and the relief valve will spit a little air out. This relief valve just protects the airbag, so it's a small price to pay for the protection and performance....imho.
I had my dealer install my Goosebox, but after getting it home, I found that it was actually a little to close to the truck toolbox, so I lowered the Goosebox one set of holes. I could have saved money by ordering it from Amazon or Etrailer and just installing it myself. You would need some strong help for the first install. Once installed, it can be moved up and down fairly easily by yourself.
No matter how you get it installed, hold onto your original pinbox. A few years down the road, you can move the Goosebox to the next trailer. Oh yeah, "IF" you install it yourself, make sure you have access to a torque wrench that will handle 210 ft/lbs. my dealer just tightened the bolts "till it felt good". When I lowered it, I used a torque wrench. 210 ft/lbs is a lot of torque to achieve unless the wrench has a handle longer than 2'. Or use a torque multiplier. I would think most rental companies would have those tools. But, do not skimp on this step. That 210 ft/lbs is a critical step.
I've only used the Goosebox for maybe a thousand miles or so, but I've been very happy with its performance.
