Hi
I know this may sound like an odd topic, I'm looking at the pro's and cons of Discovery 3 vs a cruiser. I am aware you won't go wrong buying a cruiser. However, they are big and hard to get into for little old ladies. Whereas the Disco 3 is medium size good power etc and eazy to get into.

Basically we are looking for an alternate tow vehicle for 2.5+ ton van ad would welcome the input from those with experience, particularly in the disco 3.

Look forward to your comments

Cheers

Seriously, the weight of any trailer being towed should not exceed the weight of the "prime mover".
You could have problems if an insurance claim is ever lodged.
Good luck

No - the weight of the trailer should not exceed then manufacturers designated tow capacity.

A Disco will tow a 2.5t trailer with ease.

If I'm not mistaken, a Disco 3 is heavier than 2.5t anyway.

Although I only drive a landcruiser troop carrier my son owned a discovery 3 for 3 years before migrating to USA and he only has praise for that vehicle with no problems at all and a great resale value.

There was a post yesterday from a disco 3 owner with a broken transmission from towing a big van, have a look back over the last few days.
I agree with Brian that the tug should exceed the weight of the towed vehicle, towing up to the manufacturers limit might be legal but I know what will be doing the steering when things go pearshaped, the heaviest!!!

A Discovery is heavier than A RR Vogue SE?
I somehow do not think so.

I agree that a Discovery WILL tow a 2 1/2 ton trailer and perhaps so would a mini minor on the level for a short distance. But as Ozhumvee states if you get into trouble the trailer will win. Explain that to the insurance people if you can.
A traffic cop may have a thing or two to say about it too.
What about braking capacity?
Just thiMk for a minute or two.

The Disco 3 can legally tow 3.5 ton, those rules about the vehicle can only tow no more than the weight of the vehicle has been out for a long time.

Please read my original post again. Move your lips if you need to. I said SHOULD.

A mini Minor licensed and insured and a 5 ton trailer licenced and insured may be driven. No-one but a fool would try to drive iaround Australia with it though.
There was a recent advertisment for a 4 wd ute moving a four engine jet airliner. So it can be done but it should not.
The problem will only arise with an extra heavy trailer will be in cross winds, braking downhill. and emergency braking from a high speed.
That is why road-trains can only be driven on approved roads.
Or have you seen one in George Street Sydney?

I apologise. The latest model Discovery now weighs "almost 3 tons"
The previous model weighed in at a gross of 4576 pounds or 96 pounds over 2 ton Imperial measurement.

I still feel it would be risky for the older model to tow a 2 1/2 ton trailer.
I would not.

Hi Racey,

we have a Disco 3. We tow a Kedron 3.5 tonne van with it. We have not had a single problem with the vehicle so far as towing goes. We just had the suspension bushes replaced on the front end, under warranty. I suspect that because we have a steel 'roo bar and winch on the front the bushes wore quicker than normal. Same thing happened to my Pajero a couple of years ago.

The Disco 3 has proven to be an exceptionally capable vehicle, has given better than expected fuel economy (average 16.5 L/100 when towing the 'van), is extremely comfortable, has had moderate servicing costs and looks like new after 3 years of pretty hard work.

We like the Disco so much that we intend to buy the Disco 4 now that they have been released.

The 2.7L V6 diesel is bullet proof and the adaptive transmission takes care of towing. You just put the box into drive and let the gearbox do the thinking.

At first I though the Terrain Response control was a bit of a wank but now that I have used it extensively for off-road work, I have changed my mind - it's fantastic! In three years we have never bogged/hung up or failed to proceed for any reason.

We've dragged the 'van up the Gibb River Road, Kulumburu Rd, Savannah Way, Plenty Highway, just to name a few - no problems. Water crossings - no problems.

Those who talked about the tow vehicle weight obviously aren't aware that the Disco 3, loaded with fuel, driver and a passenger and a moderate amount of gear weighs about 3.2 Tonnes. Definitely not a case of the tail wagging the dog if you are only going to pull about 2.5 Tonnes.

I hear that there are a few really good HSE specification D3's coming onto the 2nd hand market atm and also some good clearance buys as the new model rolls out.

I say, go for it!

Cheers

Russ

Hi Racey,
I am the proud owner of a Disco 3 HSE 77 model and a member. I notice a lot of people on this forum rubbish the disco 3 and i bet they haven't driven one let alone been a passenger. I have towed a Kedron c/van around Australia[weight over 3 tonne] without level riders, It's my 6th disco.
Talk to any disco owner and you will get the same answer they are great

I was in no way bagging the disco 3, am actually considering buying one down the track as a second vehicle.
I am of the old school that was taught that the towing vehicle should weigh more than than the towed vehicle which due to simple physics would seem to be the logical thing to do.
When things go "ti!s up" the greatest mass will have a greater chance of control.
There have also been problems with transmissions on this and other forums when constantly towing heavy loads long term.
While I was also aware that they were "heavy" I wasn't aware that they were that heavy.

Whqt about the new triton and nissans that can tow 3 ton.
No way they would way that much.
If you did not have electric brakes I would think you would be in trouble but it would be no different than a train.

I agree with Ozhumvee, for piece of mind and to try and save premature wear, an ideal situation is where the weight of the van is well within the towing limits of the 4x4.....not at the extreme end of it...

Land Rover for one are notorious for having high towing limits....on a 4x4 thats got no more power ( mainly talking about the earlier non Disco 3's) or weight than most of the opposition ??

If you have a limit of 3 ton and the van weighs 2.8, then you know you are going to go over the limit ( and be illegal ) by the time you add water , gear etc etc ..

If you must have the heavy van, then buy a bigger vehicle to tow it...

I tow a CT, and I personally like the idea of having 1/2 to 3/4 the weight of the upper limit on the back.....

Not sure I can understand your argument. For one, despite what a lot of you seem to miss, is that the D3 is only marginally smaller than the LC200 in external dimensions, has a bigger payload and has both more power and torque than the much vaunted LC100 but nobody goes on about the LC100 being unable to tow a big van...???
So what is your suggestion of a bigger 4WD to tow a big van then?? F250/Chev Silverado.

As to the van weighing more when loaded but come on, the ATM is on the van compliance plate and THAT is what determines what you can tow it with not the TARE.

If the LC200 can tow a 3500kg van,eg Kedron ATV then so too can the D3 and just as capably. And you will note I have an LC200 and love it but when it comes to towing, I remain unconvinced about LR's prohibition of the WDH on the D3. As I have said many times before, I don't care how high you raise the rear with self levelling suspension, you can't transfer the weight from a heavy TBM <150kg back on to the front without a WDH of some kind, simply not possible.

The Vehicle Towing Mass Guide list the LR Discovery as having a maximum tow eight of 3500kg with a max ball weight of 350kg.
For 'Off Road" work this is drastically reduced to Max Tow eight 1000kg with a max ball weight of 50kg. LR also don't recommend the use of a WDH with this model. Will they never understand what a WDH does. The question of WDH has been raised throughout the world by vanners, but LR still can't seam to get their head around what they do.

That is because the suspension takes into account the load at the rear and compensates accordingly - it effectively has a WDH built in - we do need to keep up with the times and not live in the dark ages.

So what you are saying is the geniuses at Landrover have devised how to defeat the laws of physics

EG for every action there is an equal reaction

That is if you put weight on one end of a seesaw it will go down and the other end will go up and no matter how far up you push the pivot point ( the rear suspension) it wont return any weight to the other end (front suspension)

and yes I understand how full air suspension works I drove buses with it.

Racey,

There has been regular discussion on the topic of LR's self-leveling suspension and weight-distribution hitches (WDH), which LR says must not be used on its vehicles.

If you were not planning to tow a heavy caravan, you could toss a coin to decide which of those two vehicles to choose. But you ARE going to tow the van and you would do well to understand what the WDH does before making your choice.

Try here for starters -

http://www.caravanersforum.com/viewtopic.php?f=2&t=5709

Garycol could do worse than check it out too.

There is plenty of other information on that site, all of which suggests that a WDH is a bit like insurance and seat belts: it's highly probable that you can get by without all three, but you should ask yourself if it's worth the risk.

Given that self-leveling LRs are incompatible with WDHs, I think your choice of tow vehicle becomes obvious.
