Almost any V6 SUV should be able to tow a 2200# boat. I had been doing a bit of research, because I think my 1400# boat is pushing close to the limit of my 4 banger Subaru, which lists a max of 2000 or 2400 pounds, depending where you find the spec.
As I recall, most 4 bangers max at 2K, a V6 such as Honda Pilot gets you to 4K, and the Nissan Xterra does 5K because of beefier trans for V6, and real frame as opposed to uni-body. And the Xterra is the cheapest list price of Toyota Venza, Highlander, Ford Escape, Kia Sorento, Jeep Cherokeee, Honda Pilot, or Hyundai Santa Fe.
Right now, I wish I could trade the Forester for a Xterra! Based on my recco, a friend bought an Xterra to tow his 16' Wayfarer. Sure, it's overkill for a little Wayfarer, but far better than the Acura Integra he was using! So far, he loves the Xterra, but maybe not the mileage so much...
