How to increase the towing capacity on a Nissan Patrol?

I have a Nissan Patrol that I use for towing my caravan, but I'm finding that it struggles with heavier loads. Is there anything I can do to increase its towing capacity?

One way to potentially increase the towing capacity of your Nissan Patrol is by upgrading the suspension system. This will provide better support and stability when carrying heavier loads. You can also consider installing a weight distribution hitch to evenly distribute the weight across the vehicle and trailer.

Another option is to install a performance chip or tuning module. This can improve the engine's power and torque, allowing it to handle heavier loads with ease. However, be sure to research and choose a reputable brand to avoid any potential damage to your vehicle.
