Gross Vehicle Mass

Thats why you need to talk to the people who will know for sure.
Mods don't have to be done prior to the first rego in the NT unless it is different for weight increases on vehicles with a GVM of under 4500kgs. Heavy vehicles can be weight modded at any time. Unless it has changed or I am wrong.
Go and ask the blokes at Goyder Road.

Or ring the test shed, sorry but I only have the Alice Springs number because I am south of the Berrimah line 8951 5297.

I think you can upgrade GVM after first reg but it's only valid in state of registration? Maybe I'm thinking of something else though.

I've just submitted a query about weights to ACT motor registry. On the rego papers it says 2320 kg (2012 automatic, diesel, GXL). Toyota say 2330 on their data sheet. But I have a tow bar, tongue and ball fitted prior to registration ... so have asked what the 2320 actually represents.

Quote Rrob: so have asked what the 2320 actually represents.

Answer Skywalkerrun:If GVM is "2320Kg" on the rego papers then that is the maximum weight that has to be followed and that means that when the vehicle is fully fueled/ all occupants cargo etc including the weight of the trailer on the tow-bar that it can not exceed "2320 Kg".

Your maximum "combined weight" is when you put both the vehicle and trailer on the weight bridge as one. (fully loaded with passengers etc).

If your vehicle is within total GVM (Not including combined weight) but either your front or rear axle limit has been exceeded then you have to remove some of your cargo or ditch a passenger to bring the axle maximum payload back within its maximum payload limit irrespective to if the total GMV is within maximum weight (Hence why they do GVM "then" weight the front and rear axle separately).

The more accessories that are added the less cargo can be carried. (That is why you see heavy goods trucks with alloy rims as appose to steel rims as it allows them to carry an extra pallet or two of cargo).

Example in detail explained below.

Hope this helps.

Interesting topic for a thread. Clearly unless you don't mind the vehicle being overweight, you cannot fit too much gear into, on or behind if you are accessororised to the hilt. The GX can handle 150kg more gear thanks to loosing the rear seats and the bulky panels that go with them. If you are pushing the limits with weight, keep in mind that if you stack and the vehicle looks like it would be overweight the insurance company will be trying to get out of paying.

oops ... not clear enough with my post. The 2320kg is the tare (kerb) weight. The GVM is 2990kg - giving a 'legal' load of 670kg. I was advised by motor registry that the weight (2320) was supplied by Toyota, however I'm sceptical that the 2320kg includes the tow bar (Toyota list a 'standard' GXL diesel as 2330kg), meaning we have to add in the tow bar to calculate our total load.

Like many others, we go very close to GVM by the time a full tank (135kg) + bodies (130kg) + tow bar + cargo barrier leaves around 350kg available for all the other stuff needed for a couple of months camping - so have started the process of finding out about a GVM upgrade ... not a quick option, nor cheap.

Skywalkerrun answer: My apologies to you as i clearly put GVM next to your quoted kerb weight of 2320kg which "is" the correct kerb weight if your vehicle is a manual but you stated that your model is an auto!..... I believe this is where there is a discrepancy with the rego papers as the auto "is" 10kg heavier.

Here is what i written about vehicle weights a month prior on another thread.

Sorry i didn't realise where the discrepancy was back then but it is obvious now i look back!

Skywalkerrun

thanks - now the 10kg difference makes sense

But the tare weight shown on my cars rego papers doesn't. I guess they show the weights for a 'standard' vehicle and not the actual weight of the car as registered (with or without options).

I'll continue the search for costs / issues with a GVM upgrade.

Thanks for sharing the results of your research.

I believe that what has probably happened is that when the rego papers was first admitted when the vehicle was being registered for the first time they probably used the (Kerb) Tare weight for a manual gxl instead of the Auto gxl. This is where i believe the discrepancy is! Need to go back to the registry and check and make sure your vehicle is registered as an auto.

Should actually show it on the actual rego papers!

Does the GVM of the vehicle include the weight on the tow ball? If it does then if you have close to the maximum 250kg download on the towbar and two people in the average Prado then you would have no capacity to carry anything else.

Answer skywalkerrun: I believe the weight onto the tow-ball affects the GVM As the GVM can not be exceeded (Including the axle ratings front/rear in total load).

For every extra"s (bull-bar/winch/battery/tow-bar/roof-rack/heavy duty tyres etc,etc added to the vehicle removes your ability to carry/pull more weight.


EG: Turbo Diesel "Manual" GXL Prado 150 series stock standard out of the box

Kerb weight (kg) ================= 2320 (Kg)

Gross vehicle weight rating (kg) = 2990 (Kg)

Gross combination mass (kg) ====== 5360 (Kg)

If Gross vehicle weight rating is 2990 (Kg) but your vehicle actually weighs in at 2890 with neither axle (Front/Rear) overloaded and you have room for an extra 100kg to be added onto the rear axle then that means you are only allowed an extra 100kg down-force weight onto the tow-ball.

Lets not forget that the total Gross "combination mass" is (kg) = 5360 (Kg)...

This means you subtract 2990kg from 5360kg which gives you 2370kg allowed to be towed by the vehicle (Braked)... The extra 100kg down-force was added to the tow-ball. (All trailer weights made-up to help explain the formula).

If your vehicle its self is lighter than the GVM of the vehicle then that will allow you to pull a heavier trailer but you can never exceed the rating of the tow-bar (Usually 2.5ton Braked).

I weighed the hayman reese towbar before fitting it, including bolts and washers, tongue and ball, comes in at 28Kg.

Answer skywalkerrun: Maybe a heaver bar than OEM but at least you know you wont loose the trailer if the lug was to snap! Lol... If the lug snaps on the OEM the snatch chain goes with it!!! Lol ...... Ooooooooh What a feeeeling!

Some info on axel ratings below before someone ask's.

Axle ratings on the 150 series is in the owners manual (pg288)

Axle ratings on the 120 series is in the owners manual (pg252)

Prado 120 series

Kerb Weight =========== 2010-2190 Kg
Gross Vehicle Mass ==== 2900 Kg
Front axle load (max) = 1290 Kg
Rear axle load (max) = 1800 Kg

############################################

Prado 150 series

Kerb Weight =========== 2210-2435 Kg
Gross Vehicle Mass ==== 2990 Kg
Front axle load (max) = 1450 Kg
Rear axle load (max) = 1800 Kg

Has anyone in Vic got a GVM upgrade done on a 150?

ARB do GVM upgrades for some vehicles but the Prado isn't on the list yet. I can't imagine it would be far away though.
