Question:

Hi, I have a 2004 V6 4Runner that is stock I added a brake controller and I recently purchased a 20025 2720 SL trailmanor because it folds down to have less airdrag. Under what weight and tongue weight can I safely tow this camper without needing a WDH? The dry tongue weight is 392 lbs and GVWR is 3000lbs. My car doesnt support WDH and would have to get a new hitch for it. Thanks!

Hi Gian,

Thanks for your question!

Unfortunately, I can't give you a specific weight threshold for when a weight distribution system would be needed or safe when towing with your 2004 Toyota 4Runner. If there is a specific number, it's going to be manufacturer driven and can typically be found in your owner's manual or by contacting Toyota directly.

As a general guideline, we recommend using a weight distribution hitch when the loaded trailer weight exceeds 50% of the tow vehicle's weight. Depending on the trim level and drivetrain, a 2004 Toyota 4Runner weighs between 4,000 and 5,000 pounds. Based on the trailer weight information you provided, your camper would exceed that general guideline.

A good way to test this would be to tow the camper some and see how it feels and looks. If it doesn't feel safe while driving and you are experiencing sway, or if the trailer is causing your 4Runner to sag excessively, this is a good indicator you may need to make some adjustments to your system.

As you mentioned, it also appears the factory hitch on your 4Runner is not rated for use with a weight distribution hitch. If you decide you'd like to use one, the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # 13445 is a confirmed fit for your vehicle and is rated for weight distribution.

Installing the Curt hitch does require relocating the factory trailer connector, but you can do so without drilling by using the Curt Easy Mount Bracket # C57202, which secures to the hitch with a hose clamp-style band. To attach your trailer connector to the bracket, you'll need either:

Part # C67UR for a 7-way connector, or
Part # C42CR for a 4-flat connector.

Alternatively, either bracket can be attached directly to the hitch using self-tapping screws.

If you decide to move forward with a weight distribution hitch, I'd be happy to help you choose one that's properly rated for your setup.

Out of curiosity, what kind of trips do you have planned with your camper?
