Most vehicles on the road today are Unibody and most have no issue with using a WDH. Unsure why you think a unibody can't have a WDH.

In your MDX's case the vehicle's 500lb tongue weight limit is the trump card over your Class IV hitch's rated capability.

The MDX's specified 500lb tongue weight maximum 'suggests' to me that the vehicle's OEM Class IV hitch was intended to be used in a Weight Carrying mode, not Weight Distribution with a WDH.

I agree, the best you can do with the X20E is confirm all your loaded weights and stay within your specified weight limits.

No, your not missing the boat..., your asking all the right questions.

Bob
Thanks for your input. That is a strange disconnect that you point out between the Class IV hitch and the 500# max tongue load.

The Big Guy gave up months ago and is just waiting for me to give him the "all clear", and I am getting worn out. Those two jetski's are beginning to look good.

Will still talk to Equalizer to see if they can shed some light on this. Even our dealer is confused.

Geesh.

Not all unibody's are created equal, because vehicle unibody design platforms vary. The WDH is designed to transfer weight via force leveraging a vehicle's receiver hitch attached to the vehicle 'frame'...., unlike the conventional full "body-on-frame" constructed vehicle the "unibody" construction reacts differently to this forced WDH leveraging. To-date, many auto manufactures (where applicable) do not recommend the use of a WDH with specific unibody vehicle platforms.

Yes, WDH manufactures have brought "lite-duty" WDH products to the market, but when utilized the importance of proper application/adjustment is critical.

I believe Toyota still manufactures the most conventional full "body-on-frame" platforms in their SUV product line-up...., but in the case of the Tundra pickup it's robust hybrid construction is "similar" in design to that of a conventional full body-on-frame design except it's sectioned, I've heard it described as a hybrid unibody-on-frame.

Not sure if I'm interpreting the use of the term "disconnect" correctly...., but my intent was to project that in most towing applications a tongue weight less then 500lbs doesn't require the use of a WDH, and/or a receiver hitch with a WD mode.

It's not uncommon for a vehicle manufacture to incorporate a OEM receiver hitch that is rated higher then the same vehicle's towing related specifications.

I have never heard of it reacting differently. I have searched endlessly without finding anything. Is there a report you have found.
What are they saying that there could be a failure in the unibody using a WDH?

350lb base tongue weight + 40lbs propane + 50lbs dealer-installed battery + 80lbs Equal-I-Zer hitch and you're looking at over 500lbs on the hitch -- with a WDH, some of it will get transferred off the tongue, but as you can see the base tongue weight is pretty misleading. Plus note anything you carry in cargo area of the MDX behind the drive wheels, and anything you carry in the forward area of your HTT will count toward your tongue weight. So...I really can't comment on whether you should use a WDH on your MDX, but as you can see, without a WDH (and possibly even with one depending on how you're loaded), you may be over the tongue weight limit of the MDX already. Not trying to scare you, but I'd say pack lightly, take short, close-to-home trips, and enjoy what you have. You can then venture farther or upgrade the tow vehicle down the road as you get more comfortable (or uncomfortable) with your setup. Good luck!

I haven't seen any reference to a "failure", so I think the question would be better addressed by the auto manufactures that recommend not using (or not to use) a WDH on "specific" unibody vehicles.

To avoid totally hijacking "giddyup's" thread, I refer you to lurk around the different independent vehicle brand forums, the discussions surrounding the use of a WDH on unibody vehicles are plentiful. I check them out periodically for user information on towing subject matter.

To all the "helpers" who are still hanging in there:

Today, I spoke with Equalizer; Husky; Richardson's RV; and my Acura dealer.

First off: the 2013 MDX Acura MDX's unit-body was engineered with Honda's Advanced Compatibility Engineering (ACE) body structure designed to absorb energy from a collision.

If you click thru - it is basically a unibody construction.

The factory supplied Travel Stability Assistance (TSA) senses when swaying occurs and automatically applies (and releases) the brakes.

Some hitches do their work if/when swaying commences.

Equalizers prevent the swaying, so if it is properly installed and used, that TSA would never kick in. Because of this, many Acura / Pilot owners go for the Equalizer and I have no feedback on how that works.

As of now, I have no info other than from the above messages as to the Unitbody/Unibody issue. Will try Acura again tomorrow and will post what I find.

Good advice and exactly our thinking. I will have fun even if I never leave town.

But, now, I am curious as to the WDH. See post below. Did some more research.

Sounds like the "TSA" feature is more around sway control. This is common with tow packages (for example, see this on the F150 - ).

The WDH will NOT provide sway control, unless you get something like a dual cam setup (which does weight-distribution + sway).

Sounds like you're doing the proper research by contacting the vehicle manufacturer. Provide the details on the trailer that you are wishing to tow and ask them if they recommend that you tow it with the MDX. You might get a very different answer than from the RV dealer
