Weight Distribution System For 2010 Toyota Tundra And 28 Foot Toy Hauler

Question:

Hello, I have a 2010 toyota tundra, dubble cab with the 5.7 eninge and tow package. I just purchased a toy hauler which is 28 feet in lenght, GVW of 7,857lbs and a dry hitch weight of 857lbs. I was hopping you could guide me on the correct Weight Distribution System I should purchase. I was looking at part number PS49903. Is that correct and the best one? Thank you,

The first things you need to consider are the towing capacity of your 2010 Toyota Tundra and the towing capacity of the hitch. You can check either your owners manual or with the dealership to find the towing capacity of your vehicle. On the hitch there should be a sticker that states what the capacity of the hitch is. You need to make sure that the weight of your fully loaded trailer does not exceed the capacity of the vehicle or the hitch.

When considering a weight distribution system, you will use the fully loaded tongue weight of the trailer you are towing, plus the weight of any cargo loaded behind the rear axle of the tow vehicle.

I have linked you to an FAQ article that explains how to determine tongue weight. I have also linked our main page for weight distribution systems where you can select a system based on your measured tongue weight.

Based on the numbers you have given me, in all likelihood you will be somewhere between 650 and 1000 lbs on your tongue weight. Where your cargo is loaded on the trailer will affect the tongue weight. In order to keep the tongue weight more consistent, you should load the trailer the same way each time if possible, and test the tongue weight if you make any changes. A mismatch with the tongue weight would result in erratic performance. If you plan on carrying varied loads, I would suggest the etrailer Trailer Tongue Weight Scale, part # e99044.

I would recommend a weight distribution system like the Reese SC w/Sway Control, part # RP66560. This system is easy to set up, and has sway control which limits side to side movement. This system also includes the shank, but you will need to add a ball, # A-90 for a 2 inch or # 19286 for a 2-5/16 inch ball. I have linked you to an FAQ article on weight distribution and sway control.

If you are considering the PS49903, keep in mind that for trailers longer than 26 feet long we recommend a second friction sway unit. You could use a unit like the Reese Friction Sway Control Kit, part # 83660. A trailer as long as yours will be susceptible to sway caused by crosswinds or oncoming traffic. Friction sway control units need to be disengaged before backing a trailer and cannot be used on slick or icy pavement. For these reasons, I think you would be much happier with the Equal-i-zer system.
