Hi,I have a 56 plate Sorento which I use to tow a van with a max of 1550kg.It tows with ease and is very stable in traffic and high winds.Have been to France with it for the last 2 years covering about 5,000 miles nothing was too much for it and it performed admirably on some very steep sections of road.It cruises effortlessly in 5th on the motorways and copes with most hills in 5th.Averages between 23 and 25 to gallon with van on.Have had 2 (older models) Discoveries and Mitsubishi Warrior the Kia beats them for ease of towing,but if you want something for serious off roading would not pick the Kia
Cheers John
