G'day
I had a 120 series Prado as a company car which I was very happy with. I have been looking around recently for a 4WD vehicle of our own to tow around 2500kg. I have looked at Prado, Pajero, Patrol and Isuzu so far and done a spreadsheet to compare them.
One thing that has stuck out is that all except the Prado state a 3 tonne towing capacity (Prado is 2500kg). Correct me if I'm wrong but the way I see it is that some of these vehicles can probably never pull 3 tonnes legally with their stated towball download weight.
Mitsubishi for instance give a 3 tonne towing rating on their Pajero HOWEVER they have a nice little disclaimer that states maximum towball download when towed above 2500kg is 180kg. Below 2500kg it's 200kg downball load. What can you tow that's 3 tonne and only has 180kg towball download weight.
I'm basing the above on the guide of 10% of towing weight should be on the towball. If this 10% rule is close to beng correct then the 3 tonne towing capacity will hardly ever be legally used?
So far Prado is the only vehicle I can see that has a rated towing capacity of 2500kg and a 250kg towball download weight which fits into the 10% guide.
Have I lost the plot?
Cheers

Hi Pete,
I think you nailed it when you said the 10% rule is a guide.
Cheers, Bruce.

I don't know where you're getting you're information from, but the dmax/colorado sites both state 3000k.g. tow and 300k.g. downball weight. Unless you're looking at some other Isuzu?

Hi gbc
Thanks and apologies as I just rechecked my spec sheet and it does read the Isuzu has a 3000kg tow and 300kg towball download.
Cheers

Hi landseka
I agree with you about the Triton. I was really looking at a Pajero which does not have the towball download as the Triton or Challenger has.
The Challenger looks good but the smaller diesel engine put me off as a 3 litre turbo diesels is fine on the black top but it struggles towing 2.5 tonnes in off-road work.

One should read the towing guide for each vehicle as some alter payload capacity depending on ball weight.
Of course all should realise that ballweight IS part of the payload anyway.
Some obviously dont as seen in some rigs Ive passed on the road.

The Pajero can tow 3 tonne with the towball weight of 180kg. Towing up to & including 2500kg the towball weight is 250kg. The 10% rule as I understand it is/was an
unofficial Australia towing guide where in Europe & other overseas countries it's 6% hence the 180kg towball weight of the Pajero when towing 3 tonne. There are numerous points to consider & some people who are towing probably wouldn't have a clue what the weight of their van is fully loaded,combined weight of towing vehicle & van & probably exist with the rule "Ignorance is an excuse" A friend towed a full van of full laden weight touching 3 tonne. The tow vehicle was an auto Patrol 3 ltr diesel....towing capacity 2500kg....he sold the auto & purchased a manual. Some vans although loaded maybe close to 3 tonne but because of the design have a low tow ball weight & visa versa. In my view, we could all throw caution & legalities into the wind, I mean how many vehicles towing vans do you see pulled up by the authorities and are checked & weighed? BUT, become involved in a collision & write off your tow vehicle ie...$60,000 plus your van $50,000, total $110,000 & an astute insurance investigator does his or her sums & establishes the fact you were towing illegally & dismisses your claim...is it worth the risk?

G'day OREJAP
You make some good points. I took advantage of a public weighbridge in
Alice Springs and weighed the Prado fully laden with full fuel tanks and it came in at 2.78 tonnes. Went back with our Karavan in tow and weighed both and worked out we had approx 220kg download on the tow ball (250kg rated).
I was blown away when I realised all up I was coming in at just under 5 tonnes, it changed my driving habits, speed and what I should limit the vehicle to in some conditions.
It seems the Patrol, Pajero & Prado have about 600kg (based on GVM less Kerb weight). We don't have too much gear we can place after all the towing load is added. I was surprised that the 200 series Landcruiser also only has 600kg although you can have the GVM upgraded legally before it's first registered but that's another $2k plus... ouch

Hi Kimba10
I had not considered the Pathfinder and may
well do so now. The 734kg payload looks good. I just downloaded the spec sheet and a tow ball download of 250kg reduces the loaded vehicle mass below GVM by 250kg which is what I will be roughly loaded at. At 300kg a tow ball download of reduces the loaded vehicle mass below GVM by 340kg.
I have totally relied on the Patrol spec sheets as on two occasions in two different locations I have not been able to find a Nissan dealer open of a Sunday (I call them 'No-Sin' dealers as they seem to obey the Sabbath!) in my region. Each location was a typical car yard cluster with the Mitsubishi, Toyota etc... open, but no Nissan dealers.

G'day Pete,
Long time no see.
I think the 3 door Prado has a 3 tonne capacity whereas the 5 door is still 2.5.
Good luck with your search.
My D4D is nearly 4 years old.
Time flies when your having fun.

Hey Pedro,
Yes it's been a long time between drinks. The Prado short wheel base (335mm shorter) worries me as most SWB vehicles do not seem to have good control as a tow vehicles. The sway of a caravan when coming up behind it is usually a
sign of a SWB towing it.

The Pajero will handle a 3000 kg European style. Because of the design philosophy of the European vans, they are as stable as our vans with only 6 - 8% ball loading. They build their vans with no heavy items at the ends of the vans. Their vans are all centre kitchen, they have smaller front boots and they do not have items like bumperbars, spare wheels, tool boxes or annex poles hanging off the ends. If you read
this page you will understand what getting rid of weight at the ends of your van can do for the stability of your rig.
The Europeans don't load their vans at the ends. That is why you will find many European vehicles with a maximum ball weight of less than 10% of their maximum towing weight. The towing capacith of some vehicles sold in Oz is reduced reduced from the European specs to meet the Oz 10% rule.

G'day PeterD
Thanks for the article. It will take me a while to go over however it looks a good read.
My 2007 Karavan certainly does not fit into the European download weight model. We have about 10-12% towball download weight. I know the newer KK's have redistrbuted a far bit of weight to the centre.
Thanks

In my Patrol Pete, the towball download is 200kg or 8% at 2.5T
but even with 10% rule the 625 load is only reduced by 150kg to 475 load which is pretty good and even at max 3.5T tow its still ok.
At these levels I think I would be more concerned about other vehicle
stabilty issues like short wheelbase and high centre of gravity of some of the alternatives.

Thanks Robin,
It's all a very interesting mix and my comparison spreadsheet keeps expanding.
I don't feel comfortable towing with SWB.
One thing I have discovered is the Navara ST-X 550 Dual Cab & Pathfinder Ti 550 have a 6 cylinder V6 Diesel (Renault/Nissan) which has about 35% more torque and power than the most other 3 litre inline diesels on the market. They are a bit pricey however I'm sure they will pop up in the other models soon.

My mate got the first STX-550 recently and I did a bit of a review here Pete - it really has got what it takes to pull strongly and evenly , its a very good implementation, particularly the way the auto downshifs to maintain engine breaking. Quite interesting to drive it.
I don't think it will match the life cycle economy of my petrol Patrol though but its a bit early to tell on this factor.
I don't think it will have the chassis strength for tough off track towing , but as a touring tow vehicle it work
well and outperforms a R51 pathrfinder (petrol) in the family.

Thanks Robin.
I had a look at the STX-550 archive and it made interesting reading. I'm not in a great hurry at the moment so I will sit back and see how things pan out as the options increase.
I think we will see some very interesting developments by the end of this year and /or early next year. I have been looking around for a 6 cylinder engine as I feel off road towing is a bit too much strain for the 3 litre diesel turbo's.

One thing that sticks out here is the wagons typically 600kg payload vs d/cab 1000kg payload. Means loaded d/cab still
well within spec, wagon at or over spec (as most out there would be towing 2.5-3t....). Comes down to preference of d/cab with canopy arrangement (more cargo space, carry capacity, full chassis) or wagon (less cargo space, but generally heavier tare weight that d/cabs may suit heavy vans?).
