    I'm going to get an andsersen hitch if I can find the money somehow. Before you jump and and down and say "not recommended" ... Did you guys investigate how the andersen hitch works. Yes it will transfer weight to the front axle (a good thing)... probably not as much as a massively heavy locally made weight distribution hitch. I think the biggest issue will be the height controller on the land rover, it probably doesn't like the undampened springs (which is what the local weight distribution bars are). They WILL cause bouncing and oscillation of the rear axle. which probably screws up the heigh sensors on it.

    Now the andersen hitch is NOT undampened. It's not big monster sized bars flexed up to the max. It's chains fitted with bushes that will "give" rather than bounce.

    Don't worry about the height adjustment ... It'll take car of itself. I've towed with Citroens for decades. No weight distribution ... weight distribution, caravans, car trailers, box trailers ..... Throw a massive nose heavy caravan on the towbar ... it's arse end hammers down onto the bumpstops ... wait 15seconds ... it'll lift back upto normal ride height. put on some weight distribution bars, pull 'em up hard and tight.... Given it was previously at the correct ride height, it is now way to high ... wait 15seconds and it'll level back out no worries.

    What DID concern me was allowing it to settle without the engine running. This would massively torque up the distribution bars ( the equivalent of removing the springs from your car so if falls down onto the ground ..... but leaving the bars hooked up).

    If I owned D3/D4 .... I'd go for it .... worse case, you find it sucks towing with the weight distrubution hooked up .... so you unclip the chains and remove them. But still have the adjustable hitch with the rotating anti-sway ball mounted on a friction bush. So you would still have the anti-sway.

    I feel the most important thing to do when towing, is make sure the van and car are setup to tow first, before considering any device to assist when towing.

    98% of van manufacturers have no clue or desire to make their vans remotely good to tow, wheels to small, drawbars not at the correct length, axels in the wrong place and so on and so on.

    Then there's to towee, he just just hooks up the van and off he goes, cause olmate van manufacturer tells him yeah just hook her up and go, no heavier springs, air bags for levelling the car, no adjusting air pressures or even if the car will tow it, yeah she'll be fine, it can tow 3500kg, there see, it's in the manual

    I cringe every time I see people happily towing down the highway, with the car dragging it's arse on the ground, blissfully unaware of anything other than getting to where they are, going at 80kph with 10ks of traffic behind them, cause they can't go any faster or the car will wobble off the road.

    That's for sure... Some people have no idea about weight distribution and towed loads.

    The Andersen hitch is very, very smart. I'm itching to try one.

    Have a look. It's not just the bush dampened leveling, the hitch clamps to your ball so it can't rotate on it ... and the entire ball rotates inside the andersen hitch. The heavier the tongue load, the more force applied to the friction bush in the hitch, so it's much more difficult to rotate (helping prevent sway).

    People are free to make choices sometimes they make bad ones.

    On a Discovery 4 a correctly set up van and D4 combo does not require any additional help. But the problem comes from poor van design or poor setup by the owner. That "setup" can be many things from tyre pressure through to how the van is loaded.

    If you tow with a setup that does not meet the vehicle manufactures recommendation and something goes wrong you "may" have issues with any claim.

    I have many 1000's of klms with a 3500kg van attached to my D4 not once have I ever thought that I needed anything to transfer weight back to front wheels.

    My van in travel trim full of water has a 320kg ball weight. I have zero problems with how the van tows.

    If you are having problems a band aid solution is only masking the issues. Fix the problem don't add to problem by using gear that is not recommend.

    SPOT ON!!!!!!

    What frustrates me is if you then raise the issue with some van manufacturers they will tell you to fit a "masking" solution...

    It is very good that some folk can find a set up that gives them zero problems. But what about the others? I guess this is a problem for a forum, ask a question, ask it with a view that you don't want to start a war and that you are wanting a relatively specific answer, and you get all sorts of answers. Just how it is I guess.

    Thanks everyone for your inputs but I reckon if there is no further actual experience with the Andersen system then it might be time to put it to bed.

    Thanks, Simmo

    Simon, it's exactly the reasons you give.

    A badly engineered Van (load) is the problem.
    A correctly engineered Van (load) will not induce problems for anyone...

    Sticking a band-aid onto a vehicle not designed to have such a system fitted is not the optimum.

    I would not want to be the one testing the legality of the phrase "not recommended" vs "recommended".

    Do you have a van that is causing concerns when you are towing?

    Interesting read , given the max load for a discovery or rrs is (don't quote me) about 6-700 kg from memory , so when someone sticks 350 on the towball are they then reducing their vehicle load to compensate , I have seen some huge vans getting towed by some well and truly loaded landys .


    IMHO 350kg is a lot of weight to swing of the arse of any of the larger 4w4 vehicles and would be more suited to F350 or light truck me thinks , but each to there own , happy towing .

    It's nothing to do with the land rover self levelling ... weight distribution simply distributes the load across both front and rear axle. Which will always be better ( even better again.... is a 5th wheeler where the towball is slightly forward of the rear axle, so spreads it's load over both axles).

    The andersen hitch I reckon is a brilliant idea... If you just want the friction/anti-sway .... don't tension the chains .... I bet with the chains tensioned so more weight is applied to the front axle tows way better though.

    Good caravan design doesn't mean they won't sway one day. though with the land rover trailer assist

    [ame]https://www.youtube.com/watch?v=cy4vfcX_BrU[/ame]

    and the caravan anti-sway fitted to european caravans these days, your pretty safe.

    is this the ultimate anti-sway ?

    Good videos. And the 2nd one is very clever in design. Well suited to a coil sprung vehicle.

    The issue in the LR designed vehicles is the "towing" persons obsession with the concept of load levelling devices.

    No one thinks twice of packing 500kg of concrete bags in the boot and driving home. All the weight is till behind the rear axle line.

    Yet, load a vehicle correctly, attach 320kg of Van and some people "lose their mind".

    2 things a van should be:
    - Balanced correctly
    - Have effective braking

    If it has both of these then towing with a D3/4/RRS will not be a problem.

    Lifting (distributing) load on these vehicles induces potential to lose the vehicle.

    The vehicle balance over the front wheels is still sufficient, the system now detects additional load in the front, yet lighter than expected loads at the rear and when the dynamics are there attempts to compensate for an incorrect load on its suspension.

    Add to this the hitch is not designed for additional upwards force and all sorts of things could go wrong.

    ***in the LR video the vehicle shakes a dynamic load (the defender is free to move on its suspension, combined with the trailers suspension) so is more variable than the solid load of the vans suspension in the 2nd video.

    The driver then throws the trailer more violently than the driver in the 2nd video - to the point of inducing tyre smoke from the trailer... And the a Discovery easily controls the oscillations.

    Another huge factor is the choice of vehicle.

    Let's take 3 different LR for instance...All can tow 3,500kg

    Defender 90
    Discovery 4
    Range Rover Sport

    Wheel bases and weights of tow vehicles should be a primary consideration when purchasing a tow vehicle - not just "which one is the prettiest"

    If one has a 3,500kg & 6mtr+ home on wheels it comes to be logical that the longer wheel base, wider stance and extra weight of the D4 will result in a much more suitable and stable tow vehicle than using the equally rated Defender 90.

    Even the RRS with a marginal (balance/design/size) van is at a disadvantage as it shares the wheelbase of the old Disco 1,2 platform. Is much lighter and therefore slightly more susceptible to the "tail wagging the dog".

    For the really big vans - something Iveco in size is far more suitable - in 5th wheel configuration preferably..
