Another, what tow vehicle to get thread

Here is the deal. I need to replace a 2dr Tahoe for towing my X-1. The longest trip we do is a 3 mile drive on mostly flat roads. I'm looking at Explorers, Explorer Sport Tracs, 4Runners, Expeditions, and Tahoes. I have conciderd the F-150s, Titans, and the new Silverados, but I don't want anything bigger and would prefer an SUV.

The trick is I would like something with no more than 20k miles and would like to pay $25k or less. The search is getting frustrating; I am thinking of just holding on to the 2Dr Tahoe.
