Which SUV do you recommend to tow a caravan and return good mpg?

I'm currently using a Mercedes-Benz R320CDI L to tow my caravan. It's a lovely, comfortable car that tows with ease. However the fuel economy is not great (about 22mpg when towing). I'm thinking of changing cars and I'm looking for suggestions. I had looked at the Audi Q7, but the reviews were not that great. Can you suggest a car that will tow up to 2200kg (currently towing 1400kg) and return nearer to 30mpg when towing with just two passengers? I only use the car at weekends or when caravanning as I have other cars for commuting etc.

You have picked one of the best tow cars there must be with its four-wheel drive and colossal weight. If you can do without an automatic transmission, then both the KIA Sorento 2.2 R Type diesel manual and the Hyundai Santa Fe 2.2 R Type diesel manual will tow 2500kg and probably give about 40mpg solo. The automatics can only tow 2000kg.
