How good is the KIA Sorento 2007 Diesel for towing

Hi, I've just bought a KIA Sorento LX BL Turbo diesel 2007, Could you please tell me how "reliable" are they and also how good are they for towing, I heard that they get good Fuel Consumption as well, is that right? In the books it says that they can tow up to 2.8 tons. I traded in a Mazda Bravo 2001 2.5 TDI that had done over 350.000kms and could only tow 1.8Tons. I hope I've done the right thing, The KIA is a great looking car. Thanking you for your time. Ken Aikman.
