New Andersen WD hitch
A fellow camper bud showed me this. It's new and different. Anyone using one? Andersen WD hitches A U-tube video with the factory guy explaining it. You have to get past MR Truck doing his...

Ron,
I agree with your last reply. No questions there however I may not have created enough words to explain my thoughts.
When I started looking at the Andersen I was trying to apply it to my TV and TT. From this reply I came up with this.
And then
I agree and I am not questioning this. The question comes down to can the Andersen hitch create 7,800# of force in each chain used on my setup for a 1,400# TW and how much compression will that be? Is the urethane so compressed that that very small changes in compression of the urethane greatly affect the WD? It may not be as smooth as Bruce's data for load verses compression when at the other end of the force range.
From Bruce's post on the other forum
If I use Bruce's data where he used a force gage in the chain, 1/16" = 600# of chain force. If this is a linear relationship which I doubt it is, for 7,800# chain force it would need to compress 13/16" EDIT: 6-10-12 I miss-read Bruce's note. The 500 to 600# is combined both chains. The compression required will be more. See reply 2 notes down.
I have my doubts that will happen with the size of wrenches we are talking about here. This may also come down to that Andersen has a totally different thought process on what is good WD. They show a F250 in their video. They may allow the truck to take bear more of the TW on the rear axle and let the front go light.
I will have to find which poster stated he could not pull any harder on the wrench to get more WD.
Thanks
John

In my case I have an actual 1,400# TW and this hitch is rated that high. That is approx. 1,100 # at each snap up chain using 28.5” long WD bar or 5,225 ft. lb of torque into the receiver. The Anderson using it’s 8” tow ball would need 7,838# total chain force to create this.
There is some error in this as my Reese Tow beast shank is longer then the Anderson shank but it get’s me in the league of feeling what chain forces are going on with the Anderson.

For comparison, with a 1000# tongue weight and a typical TV/TT combination, a WDH would need to transfer almost 500# to the TV's front axle to give 100% load restoration.
The scales data presented by Bruce and Renojack suggest their hitches would transfer about 220-240# to the front axle at 1/4" of urethane spring compression.

I now better understand why only 1/16" compression works for my rig, as it is putting a total of 500-600 pounds of weight distributing force on the hitch. Increasing the compression to 3/32" increases the total force to about 900 pounds, which seems to be too much for my Honda.
