Santa Fe, Sorento or something else?

HI there. We have a mid-sized Hobby (1350kg) and currently tow with a Peugeot 407 SW. This is a great car when we leave the van at home, and is a bit bouncy when towing.  It is a long car with a bit of an overhang.    We do 15000 miles a year, and about 3500 are towing.

So do we go for the Santa Fe, the Sorento or something else.  I think the budget is around 20k for a second-hand but nearly new motor.

All suggestions welcome!  Thanks.
