Two reasons.
One: The genuine Land Rover towbar is not rated for it.
Two: The SLS will have a little fit at the change in loading.
Do a search for weight distibuting hitch or WDH, you will find a lot of information.
I've read the handbook about no load levelling devices to be used and took off on first trip with 2575kg GTM (25 feet 10 inches) van. Wow! FRIGHTENING! Ok till a semi wanted to pass and then un- controllable tail wagging when he was in passing mode even tho I was driving on the road shoulder to give maximum space between us - as I had always done in the past.
Pulled in to trailer expert, he was appalled when I showed him the handbook directive! A telephone call to Hayman Reece and a friction sway control was fitted with big improvement but the rig is still uncertain on the road.
We can't get enough weight onto the Disco front wheels ball weight is 230kg; incidentally pulled this van for thousands of kms with the old series 80 4.5 litre Cruiser...no worries like we now experience; the 30 to 35 litres per 100 was getting me down is why we went to a TD5 which gave us 15 litres per 100kms over 3,500 kms on the recent trip! Be interesting to do the figures next trip as I have removed the EGR valve now.
Can anyone tell me why L/Rover is so adamantly against LLH's; I believe that the new Patrols also ban LLH's.

Also, 230kg on the ball is too much. The maximum for the LR tow hitch is 150kg. Your caravan probably has poorly distributed weight (too much in the front, that much is sure, but may also be too much in the rear).
I have no such issues towing my boat that is 10.5m (~34' 4") overall on the trailer, weighs around 3000kg, but only loads the tow bar by about 100-120kg.
The bulk of the weight must be over the axles of the trailer.

There is quite a large thread done on this a while ago. The question I posed and will put again is this: When using load levellers you are transferring some of the weight to the front wheels. So why does SLS not like this? It functions fine with no caravan. It functions fine with a caravan(assuming it is with in weight limit) so why can't a caravan have level rides taking some weight off the rear?

Your towball weight is far too high, thats causing the problem (I would think).
We towed our 2,000kg boat, fully loaded (prb total 2.5t) from Sydney to Darwin behind our TD5 D2 (SLS) with the standard towing setup - no problems.
You may need to move some stuff behind the axles to get some load off the ball.

The maximum ball weight limit for a D2 is 250 kg, it is a D1 that has a 150 kg limit from memory.
In theory you are not over weight at 230 kg, having said that I have towed our 2500 kg caravan with our D2a with SLS and it is not good to say the least stability wise and I have to be very careful especially on bumpy dirt roads. It is obvious in the way the vehicle handles that there is not enough weight on the front wheels but I did not want to fit a WDH because the caravan is towed off road often and WDH limit's articulation.
Grumdriva who is a member of this website towed for thousands of klm's a 2.7 ton van, his D2 had coils with airbags and a WDH with out any stability issues as far as I know, not like mine.
I have now fixed the problems of towing a reasonably heavy van with a under powered V8 D2a Disco, I brought a TDV6 D3.
It might be an idea to PM Grumdriva, I'm sure he would be happy to assist with advice on how to set your D2 up for towing a big van. By the way maybe the easy way to find him is look in the Markest section where his D2 is for sale. It is a 99 D2 with a 4.6 V8 fitted.
I'd guess often with boats that many would have a much lower centre of gravity and possibly a 2 ton boat might not to be as long as some vans like yours. I'd also guess that vans are more inclined to catch the air off of a truck because of their big slab sides. I tried on several occasions to move more weight back to see if a lighter tow ball weight would assist in front wheel weighting and all it did was make the van cause the Disco to sway more as the tail wagged the dog so to speak.
I'm sure with some research and fiddling you will get a good set up for towing.
Good luck.
cheers,
Terry
The commonality then is that those who have towed with more than 200kg on their tow bar have had stability issues and those that tow with less don't. You do the math and make your own decisions.
As I said earlier, the rig I tow is much larger and heavier than the rig concerned and I have no issues.
The problems are too much weight on the tow bar and poor weight distribution.
Sometimes in life you just have to accept that what you are doing is wrong and you need to make the changes yourself. The addition of further technical devices to `fix to problem' only moves the problem elsewhere. That means when that solution fails the results will be more catastrophic.

I have 230kg on my tow ball when towing our 1900kg tandom van with the SLS D2a and its never given me any stablility concerns. No WDH either.
