Hi, I see your point. As mentioned, I stand corrected, it appears that an increase to the GVM, after registration, can be done and certified. Originally (pre 2009), it could only be done prior to first registration (by Lovell's). Now it appears that ARB can do it, so that the RTA/Dept Transport pass/certify it, to existing vehicles. Anyway - I think that the GVM increase is all theoretic. I don't mean there is any doubt about its validity - what I mean is, why is (anyone) doing it - to keep the 'powers that be' on their right side. Either the car is capable of handling the towing, or not. Also, don't misunderstand my apparent flippancy - I think upgrading the suspension, air bags, coils, whatever, is good - when it is for all the right reasons. These could be to make improve the 4WD experience, or to improve the towing capability or capability (or both). If it is just to get a certificate - well, I just think that is a waste of effort. The other point you raise is why (in BT's opinion) a person without "professional" experience should not tow anything over 22' with a 200 series. The "jumping around at the back" is part of it - where the OEM rear end suspension is soft - but I think BT's opinion comes from the need to be in control of a box on wheels that is significantly longer than the tow vehicle. I think that is the implication with the reference to truck driver (and their training/experience) capability to handle long loads. Apart from manufacturer's specification (ie: max. towing is 3500Kg, where GCM must not be exceeded), there is a implied "rule" that the tow vehicle should be heavier than the thing being towed - so that the tow vehicle is always in control. (This is not a "rule" at all - it is just an impression or preference in the industry). However, I have heard caravan sales people categorically tell people that their VW Golf can tow a 17' Coromal caravan. I exaggerate, but you get the point. I tow a 22' Evernew - which (by industry standards) is a heavy van. Certainly I know it is there and I have had issues that need to managed on the road, but if you drive to the conditions and take it easy, until you get a real handle on the weight and characteristics of what is being towed, you will be fine. And yes, a WDH is an absolute must. From my personal experience and from the little you have mentioned, I would suggest that you - upgrade rear suspension, to additional 400Kg capability - means new coils and upgrade shocks (ARB will automatically suggest Old Man Emu shocks). This will automatically give you a 25mm lift (I don't think there is a 'no lift' option at 400Kg, but there might be) - install air bags. Run them at 5 lbs around town (meaning no lift). When the van is on pump them up to about 22, or 25ibs. Its important to this in the right order - put the van on, put the WDH on, make it level. Then pump up the air bags so that it visibly takes the extra weight, so it might raise it about 5mm max. - just when at the take up point is the right amount of air. - if you are putting on a roo bar, I would also suggest doing the front suspension. To do the front, will mean about 20mm lift - which puts the whole car back on the right plane (assuming you have done the back). - install a TPMS system (Tyre pressure Management system) - so you can monitor the caravan tyres. They are a long way away and there have been times where people have lost one of the rear wheels and not known about, until the whole rig has become so unstable that it takes them off the road. (My last trip to Perth saw 3 vans off on the side of the road, one was a direct result of a blown rear tyres on the van - it was a BTer too...., being towed by a LC - ouch.) From all I have heard, the Roma is a good unit. Have a great time with it. Just take it easy (90KM/Hr or less) until you understand what it does and how it reacts. Try out some emergency situations, emergency braking, swerves at low speeds in a controlled (safe) environment, etc. Apologies if I am telling you how to suck eggs. Regards Geoff
