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.

- Recommend A Weight Distribution System With Sway Control For 2008 Gulfstream Ultra-Lite 21 LE
- I did some research and found that the dry weight of your 2008 Gulfstream Ultra-Lite 21 LE Trailer is approximately 3,200 lbs when not loaded. When choosing a weight distribution system, the tongue weight of your trailer will determine the proper weight distribution system. Tongue weight is usually about 10-15 percent of Gross Trailer Weight loaded and ready to tow. So I multiplied 3,200 lbs by 15 percent and came up with 480.
If you find that you will have a lighter loaded trailer, I would

- Recommendation For a Weight Distribution System on a 2002 Mercedes ML320 Towing a 4,260-Lb Trailer
- A weight distribution system is a good idea any time you are towing a trailer that is at least 50 percent of the tow vehicle weight. You will want to check the hitch on your 2002 Mercedes ML320 to make sure it will accept a weight distribution system.
To choose a weight distribution system you will need a system that has a tongue weight capacity range that encompasses the trailer tongue weight loaded and ready to tow, plus the weight of any gear in the tow vehicle, behind the rear axle. Since

- Weight Distribution System for 30 Foot Aerolite Travel Trailer with 808 lb Dry Tongue Weight
- The effective range of the W/D system you choose should encompass the fully loaded and ready to tow tongue weight of your trailer, which includes anything stored behind the rear axle in the cargo area of the tow vehicle (as you stated). You are also right on the money with needing to include the weight of the propane tanks and batteries. Given this, the RP66083 would have insufficient capacity to handle the tongue weight of your trailer.

- When choosing a weight distribution system you will need to go by the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the tow vehicle.I did some research and found that on a 2012 Dutchmen Aerolite 195QB the gross trailer weight is approximately 5,400 pounds. Tongue weight is typically 10 to 15 percent of gross trailer weight so we are looking at 540 to 810 pounds.

- Weight Distribution and Sway Control for a 2011 Ford F-150 and 24 Foot Car Hauler Trailer
- Based on everything that you need a system to do going with an Equal-i-zer system will be the best bet. You are correct about the dual-cam system being closer to the ground and not as easy to remove to tow with the motor home.
The Equal-i-zer systems do use metal on metal contact to prevent sway. With any sway control system there is going to be some noise but it is not constant noise unless it is constantly working to prevent sway. The dual-cam system would offer the best sway control but th
