How To Determine If A Weight Distribution System is Needed On a Trailer

Question:

I am trying to determine if I need a weight distribution hitch. I have a 16 foot enclosed trailer that when loaded is between 4000 and 4500 pounds. I tow with a Chevy silverado 1500. When I attach the trailer, the truck sits level and pulls fine but Ive had a friend tell me I need the wdh. Do you have any thoughts on my situation? I thought that a wdh was to help truck sit more level. If you think I need one, could you recommend something.

Typically we have a couple indicators that help you figure out if you are in need of a weight distribution hitch.

1-Your trailer weight (GTW) is more than 50 percent of your vehicle's weight (GVWR)
2-The rear of your tow vehicle sags when the trailer is hooked up
3-You experience trailer sway
4-Your tow vehicle's headlights point upward
5-You find it difficult to steer or stop your rig
6-You want to tow to the highest capacity allowed by your vehicle's trailer hitch

If you find any of these to be affecting you while towing, I would definitely recommend a weight distribution system. To figure out which system to pick out you will want to determine your trailer's TW (tongue weight). Typically TW is about 10-15 percent of your trailer's weight, so for your trailer we are looking at 400-675lbs depending on how it is loaded. It's important to note that the weight of the contents that you will carry in your vehicle behind the rear axle will also be included in this number.

The system I would recommend for a 400-675lbs tongue weight is Reese Strait-Line # RP66083. I like this unit because it stops sway before it starts and it has a tongue weight range of 400-800lbs. The Reese Strait-Line prevents sway before it starts. It uses a dual cam sway control which is the most effective on the market, because it applies constant pressure to realign your trailer behind your tow vehicle. It is lighter than many of the other systems and has a more effective sway control than other systems like the Equal-I-zer. The only additional item you will need to complete this weight distribution system is a hitch ball w/ 1-1/4 inch diameter shank. The two of the most common ball sizes are 2 inch # A-90 and 2-5/16 inches # 19286.

I have linked a few help articles as well as a video of the Strait-Line System for you to check out. If you find that your TW is different please let me know and I will be more than happy to help you find a system that will suit your needs.
