Hi all! As we are planing our trip around oz, I need to know more about the vehicle I want to tow our 21ft Kedron Topender. I want to buy a 76 series gxl landcruiser and I am thinking I will need a GVM upgrade to allow me to carry alittle more in the wagon along with the tinny on top, drawers, fridge, outboard?, Tools, etc. The Kedron has a small payload of about 500kg approx. To me, we will have to travel with water tanks empty has they hold 300kg. With such a small payload, thinking might have to fit more stuff in wagon. Does anyone know the axle weight ratings for the 76 gxl. I can't find it anywhere on toyota brochure or anywhere on the internet, and has anyone done the GVM upgrade on the 76. With engineer cert. I also don't want a hard ride when van un hooked. Any reccomendations on brands of suspension upgrade. Cheers! John

Hi John

76 Series Weight Rating is 3000 kg with a kerb weight of 2230 kg, which should mean that you can load it up with about 700kg of stuff and still be legal.
76 Series specs

Some people in the past, on other forums have recommended WA Suspensions. They can upgrade the GVM to 3500 kg for the 76.
WA suspensions

Hope this helps

Any GMV upgrade will by its nature give you a harder ride when unloaded. I chose to go half way and get heavier springs by not all the way to GMV upgrade. I still have a springy suspension but not rock hard.

My friend bought a ute with a GMV upgrade already done but drove with no load usually and ended up selling it as it was just too hard. Of course utes behave a bit differently to wagons. With no load on the tray gets a bit too light.

Thanks for reply. Worth a thought. What kind of suspension did you go with?

I chose a 400kg upgrade but without GMV plating and have airbag suspension that can be used.

I went with West Coast suspensions here in WA and changed the suspension from toyota 6 leaf + 2 helpers to 8 leaf + 2 larger helpers. The 3900kg GVM upgrade is 9 leaf + 2 helpers but they are a heavier leaf.

After having a chat with the installers I decided not to have the GVM upgrade as I only have the camper on for a short time. I still ponder my decision but after my mate selling his ute because it was so stiff I am happy with my ride comfort.

Hope that helps

Cheers

It seems people are getting confused with a GVM upgrade as opposed to fitting just heavy springs and airbags.

GVM upgrades are a legal documented process engineered to increase the vehicles carrying capacity above factory specs.

In most GVM upgrades the springs and shockers/struts are the same as what you would get in the after marker suspension manufactures upgrade.... the differance being in most cases is you can safely carry the same weight as if the vehicle had a GVM upgrade or just heavy duty suspension.

But what changes is one is legal and on isn't and seeing probably 90% of 4x4's touring or towing caravans are over weighted from factory specs if anything happens your in the dog house.

I think in the near future the state DOT inspectors will start pulling over 4x4's and caravanners and weighing them issuing defect notices and fines.

We're getting a GVM upgrade done at the moment, the parts used are the same as there heavy duty 2 inch lift but the GVM upgrade is $1800 dearer.. Why? one is complied and one isn't.

In my way of thinking it's better to do it legally with a GVM upgrade then risk the chances of fines and in worst case insurance claim refusals.

Having a GVM increase doesn't always mean the vehicle will ride any harder then one with heavier springs or airbags.

Also what a lot dont consider is that the Ballweight of the van is part of the cars load.
EG if your vehicle has a payload of 700kg and your ballweight is 200kg you can then only put 500kg in the car.

That includes fuel,you and mum, the kids and whats left can go in the back.

So maybe the tinnie the outboard and a few more bits will have to stay behind if you want to stay legal.

As well an increase in the GVM does NOT increase the GCVM so whilst you can carry more you may have to tow a lighter van.

IE original GVM 3200kg GCVM 6600 =3400kg towing capacity

Up the GVM to 3700kg and

GCVM 6600kg minus 3700kg = 2900kg towing capacity.

This is only applicable if your running at maximum GVM upgrade weight, if your not running maximum GVM upgrade weight you can still tow at the maximum towing capacity as the GVCM doesn't change.

As long as your GVCM doesn't exceed the maximum.

Correct me if i am wrong ...

As i understand it :

Upgrading your GVM allows your vehicle to carry more ...... but if you tow then the combined GCM is still the same as what the vehicle can legally tow. So your trailer / van may end up with a lower GVM than it started with due to the extra allowable weight in the vehicle. eg: taking from peter to pay paul ......

But

Upgrading your vehicle GCM does not affect the trailer / van's GVM so you can carry more weight in the vehicle, the trailer/van is limited to what it is plated at.

As I understand it you can upgrade the tow vehicles GVM but you cannot exceed the original GCVM

AS I explained above.

I have never seen anywhere that says you can upgrade The Gross Combined

Vehicle Mass so as you say vehicle can carry more but if you

LOAD IT TO THE NEW LIMIT it restricts the weight you can tow to the

difference between your upgraded GVM and the original GCVM

Eg a 100 serTD has a GVM of 3260kg and a GCVM of 6680kg

Upgrade your GVM to I think its 3700kg max and it reduces your towable weight to 2980kg IF YOU LOAD IT TO THE LIMIT.

Does that make sense.
As you say robbing Peter to pay Paul

Overall weight limit is the same , just the distribution of it differs.

It would make sense to keep the van weight within the limits because you never know when you may load the tug up and if you have been working on a lower weight in the car you may well become illegal with all its nasty implications should the worst happen.

ok, ..... a friend recently had his VDJ79 GCM upgraded in WA, he had the choice of upgrading GVM or GCM the approving engineer steered him towards GCM. As far as i am aware it allows him to have a GVM of 3800kg [up from 3300] and tow 3500kg - his total combined weight allowed is 7200kg
