Weight Distribution and Sway Control for a 2004 Nissan Titan and 7,800 Pound Trailer

Question:

I have a Forest River Sonoma 270bhs 33 ft. Overall with a TW of 790# and a GVWR of 7790#. I pull it with a 2004 Nissan Titan 2WD with big tow package. I’m dissatisfied with the dealer included WDH w/ sway control. It’s not reducing or eliminating sag and it doesn’t manage sway at all. I’ve rearranged the way I load and added an additional sway control brake. Please recommend a WDH with sway prevention so I can tow comfortably.

On some trucks, specifically 1/2 ton trucks, there can still be sag even when using weight distribution. But there are ways to combat that. First though let's get you set up with a new weight distribution system.

To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle.

If we go by 790 pounds then Reese Strait-Line system # RP66084 is a great option. It has a tongue weight capacity of 600 to 1,200 pounds and comes with dual-cam sway control which prevents sway from starting. This system does not come with a ball so you could use the one you have as long as it has a 1-1/4 diameter shank or use # 19286 for a new one.

The dual-cam sway control is great but it requires some fine tuning to get it set up for optimal performance. Another fantastic option that does not require that sort of fine tuning is the Steadi-Flex # RP66560. This is a friction system that also works to prevent sway. Again the only thing needed is a ball.

If you have a properly rating system that is set up correctly and you still have sag then you can reduce if not eliminate the sag using rear helper springs such as # SSR-610-47. They will, at the very least, prevent the truck from sagging as much and will provide a better ride in general.

Thank you for your reply. What are your thoughts on the Husky Centerline TS and Equalizer?

The Husky Center Line Weight Distribution systems such as # HT32218 are adequate. They don't enjoy the same storied history and name recognition as an Equal-I-Zer or Reese system though. At the same time I haven't had many complaints at all on the Husky systems.

Equal-I-Zer systems such as # EQ37120ET are very popular. The tried and true design works well and a lot of people prefer this style over other friction systems. The sway control at the bars and at the head (4-point sway control) is effective and unlike the Reese systems mentioned in my previous post this Equal-I-zer system comes with a 2-5/16 inch ball. But unless you have a thin-walled socket such as # EQ70-00-4800 the ball can be difficult to install in the head. I have linked videos on both of these systems for you.
