The size of the car doesn't matter, the biggest fluctuation you're going to get is around 500lbs. Besides, just because it's bigger doesn't mean it's heavier. Hell, a 426 Cuda weighs about as much as an 00-04 Mustang... don't know the weights of the others, but probably close also.
You've obviously never heard of a diesel before.
I'd go with a 6.5 suburban if I absolutely had to tow with a SUV, though they aren't made to tow something so heavy, really.
Is it an enclosed trailer or an open one? If it's a closed one I'd suggest a truck.. get a quad cab or something along those lines so you get your interior space, then you have the box to haul something, and then you have the suspension to carry an eclosed trailer.
If it's open a SUV shouldn't have much trouble towing it.
