We have bought the 2016 Prado Kakadu in Feb this year.
We have towed with a 1 tonne camper van and didn't even notice it was there. We crossed over the range from Armidale to Port Macquarie and it handled the windy roads with ease. We travelled over 1000kms towing and still made half a tank sitting on the speed limit and driving to the road conditions.
We are yet to take it fully off road to test its capabilities, but we plan to do so in near future. We are first time a Toyota owners, and so far I would never go back. Driving local or highway you don't hear a noise. The engine is responsive. The boot space is adequate, it does get a bit tight packing for 5. We do have a roof pod that assists. We live in a colder area so the heated seats are wonderful.
There is a $30k difference between GXL and Kakadu, but if you enjoy luxury touches such as leather seating and fridge and the finishes this car is perfect. We originally wanted the Landcruiser Sahara, but was pushing our budget. So top of the range in Prado was the next best thing.
The service costs are set for the first 3 years, which is great. We have had some issues with the GPS dropping out and displaying system error. We have taken it back to Toyota but it appears it is still there. Unfortunately, it happened in the middle of Sydney and we were fully dependent on it. When we were at a set of lights, switched the engine off hoping the car would restart along with the GPS...and it did!
The middle row seating you can't fit 3 child seats in. Thankfully our eldest was legally able to sit in middle, otherwise we would have been in trouble. The third row doesn't offer anchor points, which would be beneficial in future models.
It meets our family needs and look forward to growing into it and having future adventures.
