I have a 2005 Grand cherokee with the V6 3.0CRD diesel. It is awsome as a tow car and solo. Fuel consumption solo on a run 30ish and towing 20 - 22mpg, have also had a Cherokee 2.8 auto diesel back in 2007 for a month, disnt tow with it but solo it was a nippy machine with no shortage of power. Solo driving was very similair to the Grand Cherokee. Dont know what your budget is but if it can stretch I would have a look at the Grand cherokee V6 CRD, the power and smooth box is awesome and there are some great bargains out there.
