Yea...just got in from work and came across this thread (I can't handle this one right now ) . I always look at a traditional WDH (in theory) as if it was a wheelbarrel and and you would "lift the handles" to transfer the weight to the front tires. This system to me anyways looks more of a anti-sway product but looks to be putting a lot of foward force on the shank bottom and those threaded rods/nuts.

Hi Bob,

Considering that the trailer is over 22 years old and looks as though it's seen quite a few miles, I wouldn't necessarily put a lot of credence in the so called degrade being the result of the Andersen hitch. Considering that the Andersen is fairly new I would suggest that most if not all of the wear and damage resulted from the previous hitches that were used. I have yet to see or hear of a fairly descent coupler failing. This coupler in all likelihood was going fail irespective of what hitch was used, I'm also not impressed at the bubblegum fix that they want to do....this coupler needs to be replaced....not patched up. As for the Andersen, I think it's under the microscope and before it's condemned, let's have something substantial, not a worn out, patched up, 22 year old coupler.

Ron,

What I found interesting in the Air Forum TT coupler discussion was the "condition of" forcing the coupler latch wedge up (been mentioned before), and this was being experienced by a couple of members on their newer TT's, including the member with the 22 year old TT. It was this "latch wedge up" condition that I was referring to as a "de-grade" (coupler function compromised) of the particular coupler style being referenced, but as the reader will find not all members have experienced the same condition.

I agree, in June 2012 the Air Forum thread started out like many RV forum threads on the Andersen WDH, "hypothetical" in nature. IMO the Air Forum thread has progressed to the point where we are now getting some user feedback, good and otherwise.

Bob

Thanks Bob,

I have also been following this forum and watching closely, there was another incident very early in the discussions where a coupler showed signs of cracking. The owner of the trailer admitted that the coupler was old and was in need of replacement before he installed the Andersen hitch but all the resident Engineers were lined up condemning Andersen, I swear, if it were human it would have been burned at the stake! What I find really interesting is that the two users that have coupler problems like the performance of the hitch so much, that they are looking at upgrading the coupler rather than going back to the conventional hitch.
On another matter I thought it would be a great subject to conduct a pole to see the ratio that TV OEM'S use between GCAWR and GVWR. It appears there is quite a variation in this %. I responded to a posting earlier today where my vehicle's GCAWR was 200 lbs less than a posted vehicle yet their GVWR was 500 lbs more than mine....his truck is capable of carrying 91% of GCAWR and mine is only able to carry 87% of my GCAWR. There doesn't seem to any consistency to this, the real question is who is applying more/less cushion in their calculations?

That's the million dollar question ....., all I know is that I don't want my TV to be the beta test to see how much over my limits I can go before something happens

The Anderson hitch looks like it's built on good theory.
I would just bolt through the clamps as suggested. I think in their current design, movement will be an issue.

That Hensley Lego demonstration was a little biased.
The amount he wiggled the TT with the conventional hitch was a lot more than the wiggle he induced with the Hensley Hitch :-)

JMHO

Looking forward to more experience with the Anderson system.

Doug

Hi Bob,

not sure if you've seen this site on the Andersen hitch, some interesting CAT scale data and chain torque info.

Ron,

Thanks for the link, and the CAT example seems to be reflective of a lighter tongue weight application, based on the TV and TT being identified. I've also followed the RV.NET Andersen threads since the beginning, and as I mentioned always been interested in the force-effect on the coupler......, especially with the heavier 1,200lb "plus" tongue weights.

Another area of interest for me is the long term repeatability of the product to maintain consistent weight distribution with the heavier 1,200lb plus tongue weights....., which I think may take a little more time to accumulate accurate historical data.

Bob

You're right Bob,
This is a light weight trailer, but what I find interesting and consistent with other WD hitches is the 25% shift of payload to the TT axles. This is important to me, as you know, because I don't want to be over my GVWR ratio of my truck. If this is typical then it would mean that I don't have to starve myself until May to reduce my GVW.....just kidding, but it's an interesting option. Anyway, I can't give you any info until I install the Andersen in May....it will be a new hitch on a new coupler so I will be able to identfy the wear patterns quickly. Unfortunately, my trailer will only be about 7200 loaded, so it is still light weight compared with what you are looking at. I thought there was a real heavyweight using the Andersen on rv.net...I'll have to go back a look through posts.

Ron,

The CAT scale will become your friend as it has mine, and it will tell you everything you need to know to dial in the Andersen WDH. Look forward to your CAT results (confirming amount of weight distributed back to TT axles, etc.) and feedback on the Andersen.

Bob
