With a 3.5L twin turbo hybrid, the Tundra boasts many features that will have the Aussie market excited. The only thing letting it down is the payload... if you were to tow 4500kg, in factory trim you would exceed your 700kg payload with a couple of passengers and minimal gear. Not to mention the rear axle load of 1850kg would be blown out of the water...
Increase your payload to by doing a 3.99T GVM upgrade to 1249kg! Additionally, your rear axle capacity up to 2149kg.
