Towing and WDH

I am new here and have read just about everything on the subject of using a weight distribution hitch on a 4Runner. I have a new 2013 4runner Limited 2WD V6.

I recently sold my 3000lb dry weight popup camper. Loaded with battery, propane, water and cargo, it probably weighed about 3,500 lbs. I traded in my old 2003 Honda Odyssey minivan V6 on the new T4R. I could barely tell the camper was back there. I used a Reese receiver and WD hitch when towing that camper.

Not sure if any improvements were made to the 2013 factory hitch receiver but it sure looks substantial to me. Big steel crossmember welded to the side frames and receiver bolted on with 6 bolts.

I've read a lot of opinions on the forum and it seems to be pretty divided between "no, you can't and shouldn't, or you risk killing your family if you use a WDH" and the other side saying "no problem, will work fine, don't worry about it, I've been using a WDH for years".

One post specifically says "The OEM receiver is mounted to the cross member and is not designed to take the stress of a WDH. You can twist the frame and it's not repairable." But, I don't see (or haven't found) any empirical evidence to back up that claim. Can anyone give me a link to any evidence proving that using a WDH might do damage to your T4R's factory receiver or to your family? Does anyone have photos of this? Or a document from a testing agency or mechanical engineer that proves we can't use a WDH on our T4R's? Or is this only based on opinion or a hunch?

Hoping I didn't make a big mistake buying a 4runner. Although I don't have any proof either, logic tells me that the T4R with a truck frame and bigger 270hp engine with 5,000 max tow weight should be able to handle a trailer in the 4,250 lb GVWR range without any problem. Of course I live in flat Florida, but I might want to tow up to the Smokies sometime. I don't mind downshifting and crawling up long hills at 40 mph.

Getting ready to start looking at travel trailers in the <21 foot size, but need more facts if they're available.

Thanks guys.....David

In the Canadian owners manual it specifically states you can use a wdh. It also has a page on how to set it, and talks about adjusting the wdh to return the weight on the front tires as it was before adding a trailer.

Any way you can post some pics of those pages, or a link?

David,

I too have read up a lot on the subject. If you look in the owners manual it specifically mentions using a WDH setup on Pg. 299 (2012 Manual) stating the primary requirement be that you torque the WDH so that the front fender height is the same as it was without any weight on it (which is kind of a "duh" moment). I have looked only at systems that also have sway control. It seems to be a helpful piece of equipment to have when towing. If they put it in the manual I don't see why it shouldn't be a problem when using it (since IIRC the 4th gen manual said specifically not to use a WDH system, so it's a rather significant change for the 5th gen to use it).

On the topic of other towing equipment, you may also want to consider airbags for the rear springs to help the load ride a little better as well as a brake controller. Hope that helps.

Thanks for the pdf copy of your manual. What year/model do you have? The User manual for my 2013 T4R Limited has the exact same page with the exact same photo and text, but does not have the section specifically referring to a weight distribution hitch. Those two paragraphs are gone.

Thanks...David

On the Toyota site I actually chose the manual for a 2013 4runner. They have all the manuals split into sections on their site

Thanks for the info, but page 299 makes no reference to a weight distribution hitch in the 2013 user manual. It does say that "if the gross trailer weight is over 2000 lb, a sway control device with sufficient capacity is required".

I read an article on a different website about the new SAE J2807 trailering requirements that took affect for 2013 models and indeed my User Manual mentions that my 2013 T4R meets the SAE J2807 requirements. Perhaps this new standard is the reason the User Manual no longer specifically mentions a weight distribution hitch.

The good things is, it doesn't say anything in the 2013 manual about NOT using a weight distribution hitch. :-)

Thanks....David

Must have been an earlier edition. I'm attaching photos of my 2013 manual showing the cover, Page 299 and Page 301. No mention of a WDH.

Thanks....David

Fom past reading I was under the impression that Toyota was following sae j2807 standard since the 2009 model year vehicles.

The standard was out earlier, but according to this article in Car and Driver, Toyota only agreed to adopt the standard starting in 2013:
That Dam Towing Test: New SAE Trailering Standards Explained - Tech Dept. - Car and Driver

I'm not sure why Toyota changed what was in the 2012 manual and also what was on their own website, but it's not in my manual. It would be reasonable to think if they said it was ok in 2012, it would certainly still be ok in 2013. Right?

I appreciate the links and info. I'm kind of surprised I haven't heard from any of the naysayers who are convinced for some reason that the T4R's hitch isn't beefy enought to handle a weight distribution hitch.
