Create a stable ride for your tow vehicle and trailer with a weight-distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.
Selecting a Weight-Distribution System
The tongue weight rating is the most important factor in determining which size weight-distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.
To determine the proper weight rating for a weight-distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight-distribution system.
Unique Features of Reese Strait-Line Weight Distribution
The easy-to-use, serrated washers on the Reese Strait-Line system make adjusting the tilt of the weight-distribution head a snap. This is a huge improvement over the standard pin-and-washer method, which involves piling washers - one on top of another - onto a difficult-to-access pin. The serrated-washer system lets you easily loosen, adjust and tighten a single washer and nut on either side of the head for simple, secure positioning.
The trunnion spring bars of the Strait-Line system slide into the weight-distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex, ensuring a smooth, controlled ride for both your tow vehicle and your trailer. These specially designed bars have rounded, hooked ends, making them the only kind of spring bars that can function with Reese's active-style, dual-cam sway control.
Dual-Cam Sway Control
Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. The rounded, hooked ends of the spring bars then sit in these cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.
During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

Is this review helpful?
OK, I waited to write this review until I had an opportunity to really use this product. We just completed a 950 mile camping trip around Colorado. We went up and over mountains, around curves, and traveled in the interstate. All I can say is, WOW! I wish I had purchased this years ago. We pull a 7000# travel trailer with a new F150 EcoBoost. Before installing this we were pushed around in windy canyons, semis and dealt with sway descending the mountains. This product is the real deal. I can safely travel on the interstate at speeds up to 75 MPH thanks to this product. 50034
I can't vouch for the product as yet, because I haven't installed it. I can however comment on the service & etrailers excellent way of updating the progress of the transaction. It was very efficiently & fast. I ordered the hitch on Sunday night and UPS drove up in front of the house on Wednesday about 1:30 pm and delivered it. That is great service by any ones standards. I've read the instructions some & it looks like it will take some time to install this unit. There are a number of tools that are needed to accomplish the task & not all of them are in just everybody's tool box. (unless you are a heavy equipment mechanic) which my son-in-law is, so I had access to everything I needed. A friend also bought this hitch & purchased all the tools needed to do the job so I am all set to strike out and install the hitch, as soon as it takes a turn for the better weather wise. The hitch is a massive heavy duty unit that looks to be able to handle the job with ease. When I get it installed & use it awhile I will repost a review concerning it's use & installation info including the quirks & all the things needed to measure & drill, etc. to put it to use. I again want to thank etrailer for their attention to every detail of the transaction & the prompt service & almost miraculous delivery in such a short time right to my door & in a complete state. (nothing missing) it was very well packaged to stand up to the rigors of shipping.Kudos Etrailer... 59938
Perfect for what I need it for. Was extremely pleased with the on time delivery. In will be using it for a new travel trailer, my wife and I have just purchased. Very easy to follow instructions.
The included shank is part # RP54970. It is a 1 piece unit with a gross towing weight capacity of 15,000 pounds and a tongue weight capacity of 1,500 pounds. It has more than enough capacity to adequately support the RP66084 WD system. view full answer...
The difference between the # RP66088 and the # RP66084 weight distribution systems is the style of spring bar attachment. The # RP66088 system has round bar style spring bars, these spring bars are a bit harder to install and hang a bit lower, closer to the ground, than the Trunnion style spring bars. This system is a bit more economical than the Trunnion style system and would work great for your vehicle and trailer.
The # RP66084 system has the Trunnion style spring bars, that traditionally view full answer...
If the weight of the fully loaded trailer (including water and propane tanks) is below the manufacturers tow rating of the vehicle, the Commander will tow the trailer with no problems. If your Commander is not already equipped with a transmission cooler, I would recommend one. If you could respond with the model year of your Commander, I would be happy to recommend a specific cooler.
Since the trailer weighs more than half the weight of the Commander, a Weight Distribution System is recommend view full answer...
When choosing a weight distribution system you will want to use one that has a tongue weight capacity range that encompasses your trailer tongue weight when loaded and ready to tow plus the weight of any gear loaded in the tow vehicle behind the rear axle.
With a tongue weight of 850 pounds, the 600 to 1,200 pound rating on the Strait-Line Weight Distribution System, # RP66084, would be a good choice. This system comes with dual-cam sway control which is an active system. It stops trailer swa view full answer...
The best option for a 6 inch tall frame is to go with something like the Reese SC Weight Distribution System, # RP66155. This system has the same weight capacity range, 600 to 1,200 pounds, that the system you recommended has.

Installing a weight distribution system with sway control, like the Reese Strait-Line Weight Distribution systems or Equal-i-zer systems, is not all that difficult. I actually feel that if you installed it yourself you would have a better working knowledge of the system and how to properly set it up and use it, because your trailer weight and the weight behind the rear axle in your tow vehicle may change over time and the system will need adjustment.

The reason this Strait-Line Weight Distribution System # RP66084 says it is only rated for Class II and IV hitches is because this system is designed to be used on a hitch with a 2 inch opening. Typically, the Class V hitches have a 2-1/2 inch opening, but since your hitch has a 2 inch opening it would work well for you.

The difference between the Reese Weight Distribution Systems, # RP66074 and # RP66084, is that the RP66084 system includes the adjustable shank and the # RP66074 system does not. If you choose to go with RP66074, then you will also want to get the Reese Weight Distribution Shank, # RP54970, and both systems will require a hitch ball, # 19286.
It is very important to verify the gross trailer weight and the tongue weight of your trailer before purchasing a weight distribution system. The tongue view full answer...
Dual-cam sway control weight distribution like the part # RP66084 that you referenced is one of the best options for reducing trailer sway because it is the only system to proactively work to prevent sway before it starts. Another advantage dual-cam systems have is that they can be used in inclement weather unlike some of the other friction-based systems.
However, the most important weapon you have to prevent sway is proper trailer loading. Typically, sway is cause by not having enough weight view full answer...
Your trailer is on the high end of weight distribution capacities but we do have several systems that will work for you. The first thing you are going to need to do is determine the total tongue weight by taking the tongue weight of the trailer when it is loaded and ready to tow plus the weight of anything added behind the rear axle of the tow vehicle.
The best system for you is most likely going to end up being one that is rated for 800 to 1,500 pounds tongue weight like # RP66130. You will view full answer...
The dual-cam sway control brackets on the Strait-line weight distribution system, # RP66084, do require drilling into the trailer frame but the spring bar brackets do not. They are held in place with set screws.
If the active air suspension system can be easily deactivated, that would be ideal. If it cannot be easily turned off, you will first connect the trailer, then let the active air suspension system adjust. Then you will hook up the weight distribution spring bars. This may cause the sy view full answer...
With any weight distribution system you will want to remove the spring bars every time you encounter any tight maneuvering situation. So if you were reversing your trailer and the trailer did not swing too far to one side or the other you should be fine, but I still would recommend you disconnect the bars under most normal reversing circumstances just to be safe. view full answer...
