The greater the towing capacity, the more flexibility you’ll have when towing. A four-wheel drive vehicle is essential, and a ute or SUV is preferable over a car. There are plenty of utes which will tow three tonnes such as theToyota Landcruiser, Range Rover & Land-Rover Discoveries, Holden Colorado,Nissan Safari/Gran Road, Ford Ranger, Toyota Hilux and Mazda BT-50.
If you need to tow two horses then you might want to look for a ute or SUV that tows 3.5 tonnes just to be safe as two horses will be around 1500kg and your float could be up to 2000kg.
Check the maximum towing capacity of your car to check you’re not exceeding it as this could invalidate your warranty, your insurance in the event of an accident, or even seriously damage the vehicle.
