Anderson Hitch with Long heavy trailer?

I recently used an f150 ecoboost w max tow to trailer my XLR hyper light 29 about 8k from Ohio to Seattle -- and I can tell you the Anderson defiantly adds weight to the front axle -- my first try - I did not have it assemble correctly and got to see first hand front end of truck bouncing all over them cranked down on bushing and you could see truck leveling out - my first attemp I did not have hitch setup so that truck and Trailer where level this is critical.

Here's some instructions updated


Very impressed w ease of use of Anderson hitch - make sure your truck and TH with TH on truck - make sure they are level together before any other adjustments

Move adjustable ball hitch up or down to get level (I had to turn my hitch bracket upside down to get level)- this will save you lots of time - plus the hitch will be working properly from the start this way --- or you could do the way I did and really see how different adjustments made huge differences ( don't recommend lol)


Once level and hooked up install chains to TH make sure to put bracket as far back w no threads showing DO NOT TIGHTEN brackets --

- once hooked up to triangle plate and plate is connected to hitch with TH Jack raise TH while connected to TV - this will create slack in the chains - when you find your not gaining any more slack move brackets back as far they will go - - make sure triangle plate is straight per picture in install guide - make sure big washers are installed before nut( backside of bushing) then tighten TH brackets in place ---

Disengage TH Jack this will tighten chains (WD system) and torque nuts to 90lbs

If your front end still seems like it's floating (not enough weight transferred to front axle) - adjust nuts - tighten one thread at a time and drive to check

Or the opposite if you feel too much weight on front axle

Done

Well I'm still with my round bar setup until I can save the money for a better hitch. It took 3 trips to the scales and a couple of days scratching my head but I finally got it setup correctly. In a few weeks we are headed from Iowa to disney world so I wanted to make sure she was setup correctly. I did add something to help with light leaf springs road master active suspension. Everything drives real nice now

I added sumo springs to the rear to assist the lead springs. Then once I welded the brackets to the frame to keep them from sliding. My setup was much better last trip with more weight than before to the front. Not going to keep playing with it to get more away from where I'm at which is happy and content with my setup.

So far this is like most of these debates:
-Lots of people like the Anderson, but few if any of them have any data to show when asked.
-Those with data to show have found that the Anderson can not return enough lost weight, unless their tow vehicle is significantly over-matched to the trailer.

WARNING: The following contains numbers, and calculations, based on sound engineering practices (trigonometry and engineering-statics). If you are not interested in such things, do not continue reading! If you simply like the way it feels, and are not interested in returning all lost weight to the front wheels, the following information is not for you!

The reasons for the Anderson's limitations are pure engineering statics.
a. A conventional WDH has essentially "rigid" bars (compared to a chain). The force is applied upward, so the normal/perpendicular distance to the pivot point (the ball) is about 2.5 feet behind the ball (the bar length). Therefore, for every 10 lbs applied upwards, a torque of ~25 ft-lbs (2.5 x 10) is applied to the hitch-head, transferring weight. And there is practically no limit to the amount of weight-transfer, which is why you have to be careful. I've heard of people transferring too much weight, and when going thru a dip a low speed, actually lose rear wheel traction! Of course, if you follow the instructions, this should never happen.

b. Conversely, the Anderson has the force applied rearward, so the normal/perpendicular distance to the pivot point (the ball) is only about 0.5 ft (less?) below the ball (at the plate). Therefore, for every 10lbs applied rearward, only ~5 ft-lbs of torque (0.5 x 10) is applied to the hitch to transfer weight. So it obviously will require significantly more force to do the same job. Fine. The chains and brackets are strong. So what!

But...there is a clear limit to weight transfer with the Anderson!
Before engaging, the chains are attached to the ball/plate area at a slight downward angle (rear to front). As you pull rearward, the coupler rises, and that angle approaches zero. The higher things rise, the less that angle, and the less efficient the system becomes. This is pure trigonometry. As the angle approaches zero, an infinite amount of force will be required to provide any further weight transfer.

Of course, if you have an over-matched truck, you may not need to transfer much weight, and this may be accomplished quickly, before the chain-angle approaches zero. This is why many with SuperDuty trucks find that they don't have a problem returning all lost weight.

But for those with 1/2-ton trucks or SUV's, the rear suspension is softer, and more upward travel is needed to return that lost weight. But the system simply can't handle that much travel, before the chain-angle approaches zero. Continuing to pull will only stretch the chain, but can never raise the hitch any further or transfer more weight.

Nice trig lesson and I have no disagreements. I used the Andersen WDH on an SUV for 3 years. My experience was that it eliminated the sway and chucking as desired. I did not return 100% of front weight and for me it was not an issue. My SUV had auto leveling and the 150# moved forward was sufficient. The most attractive feature was the lighter weight of the WDH. With a receiver rated at only 600# tongue weight, the Andersen turned out to be a perfect solution.

This is very well done... and explains why the chucking is lessened with the Anderson WDH. The force is applied upward with the bars which multiplies the force of a normal bounce, but applied horizontally with the Anderson. That tells me if the Anderson will work for your setup, it will probably tow more comfortably than a normal, bar-type WDH. But if it won't transfer enough weight... probably best to stick with bars.Thanks...

using that logic, less bounce with a 4 way vs traditional WD hitch. Since we have springs on the tow vehicle, maybe better dampeners than OEM shocks would be logical as well.

I would love to . how ever i viewed so many sites and checked out so many reviews , i honestly can't remember which one the guy had his scale weights posted ./ Today i picked up my unit and hooked up the andersen and so far so good TH handled very well . sitting at a campground now hoping to get to St.louis tomorrow and then i'lll get some miles on the hitch.

I have weighted my tow vehicle and camper recently and it was an eye opening experience. It does not take much to overload one of the several specs on a TV

Now that i have my unit on and tested . the NO SWAY works as i drove 200 miles in 30mph winds no sway even when trucks blew buy. the NO Bounce works as the roads where crap and the truck handled great NOW FOR ALL READING THE ANDERSEN DOES NOT RE DISTRIBUTE WEIGHT TO THE FRONT AXLE AS MUCH AS IT should OTHER OLD FASHION BRANDS DO it better WITH THE BARS .
not a problem with my truck as it's big enough to handle the TH i brought but could see an issue for those that want to pull with a 1/2 ton truck

That being said i'm sorry for assuming it did it all even though I've seen the weight sheets . IT does not . but i won't change out as the front wheels axles handled great , and it all sat perfectly level and lower in the front then with my slide in camper . so there it is xlr 29 34' total length and handled great no bounced no sway and 8 mpg sucks but had plenty of wind
