This. And the weight on the towbar.

Errol - Add the 200-300 mm to the wheelbase or add another axle. The Patrol is already too short in the wheelbase from the factory, without adding an extra cab and moving the tray back!
Had a mate with a 3 axle Patrol, it was a great setup - drove like a charm, carried a huge additional amount - and the added axle made the whole lot look like a factory build, because the standard rear axle is already close to the front axle.

Cheers, Ron.

Hi Errol,
Just read your follow up, If you have already beefed up your suspension and judging by photo of your tail heavy rig, adding 200-300 mm in the wheelbase is a logical way to go. Also looking at the tray on your rig there could be a hint of chassis bend, a good inspection would be warranted.

Tower's been fixed, that will never bend again. Have had a look, all good. Errol

Kind of agree with this you can only carry so much stuff maybe need to reduce the amount of gear and carry only what you really need and not enough to build another troll or upgrade to an F-truck or something. If you keep loading up the troll which would probably already be overloaded something is going to break which might be the rear axle or housing or chassis which has a load limit that may have already been exceeded. Depends if you like doing a lot of off roading or not a lazy axle would help but they have their downfalls as you probably already know.

Also looks like your rear axle is not in the best place for load carrying my GQ patrol twin cab has the axle near the centre of the tray and can support a lot of weight with the polyairs pumped up. I have the spare wheels in front of the cab because they weigh 35 kg each and also kept the weight down by buying an alloy canopy, under tray tool boxes and mud guards alloy tray a compromise to the strength added by steel but the weight difference is a fair amount. I would have preferred to have made everything from steel but I would probably need another 30 grand or more to convert it to a proper six wheel drive to carry it all so I compromised.
