G'day
I have a 200 series cruiser that has a GVM/GCM upgrade. It is a lovells GVM upgrade which in NSW allows us to have the cruiser @4200Kg's and still be able to tow 3500kg's. So the 900ish Kg's GVM upgrade also gets added to the GCM given us a GCM of 7700Kg's.
We are currently looking at buying a caravan that has a ATM 4500Kg's. The Tare of the van is around 2800Kg's. Is it legal for us tow this van as long as we don't exceed the our 3500Kg's? I would also assume that we would need to run the DO45 even if thought we do to with a limit of 3500Kg's towing capacity.
The van gives us 700kg's payload @ our 3500Kg's towing capacity so for us it is more than enough payload and to have the option later down the track of perhaps getting something that can tow 3500Kg's+ and having that extra payload available on tap is appealing to us.
If anyone could point me to any
information from RMS that would cover off the above I would be grateful. I would also be interested in your thoughts/advice/experience you may have.
Thanks in advance.
Cheers
Andrew

Is this your assumption, or was it a figure supplied by the engineers certifying the new increased weights for your vehicle? From what I have seen in these forums, if there is no actual figure specified by the authorising engineers, the GCM of the vehicle then the GCM remains that of the vehicle in its original state.
In other words, do you have a new GCM authorised as part of the modification deal. If it was not specified in the documentation you have received, there is no upgrade to the figure.
You will not be the first to find out after you have taken delivery of the new deal that you can not tow a caravan that is big as the ones as your vehicle originally could. Make sure the upgraded GCM figure is actually on your vehicles registered figures before you spend any more cash.

G'day Peter, thanks for your words of caution.
Yes, the vehicle has an approved GVM/GCM upgrade that is recognized and legal in NSW as this was done post rego. It is a lovells stage 2 (I think that is what it is called) and it increases the cruiser from oem 3350kg to 4200kg not withstanding the axle weight limits that the upgrade gives you. The increase of 850Kg also gets added to the Gross Combination Mass and is raised from oem 6850kg to 7700kg. I have a signed engineers report stating such and RMS have updated the cruiser's GVM to 4200kg. It is legal and documented as
well as being undertake by an authorized Lovells GVM upgrade installer and signed off by an independent and certificated Automotive Engineer. The installer is one of the bigger 4wd accessories manufacturer/installers so they know their stuff and have done many like this before.
I have double checked and tripled checked to make sure this is all legal and as I say I took the paperwork to RMS and they have updated the GVM of the cruiser to 4200kg. As far as I am aware I shouldn't have a problem with this van provided that I don't exceed the towing ATM (BTC) of the cruiser which is still the oem 3500kg's.
At 3500kgs GVM we will still have plenty of payload. I just wanted to know I was fine towing a van of an ATM 4500kg buy a car (cruiser) with an BTC of 3500kg. based on what I have found out and the above replies as long as i dont exceed the 3500kgs and use the DO45 I should be fine.
Cheers
Andrew
