As stated, just about anything will work. My SIL tows occasionally with their Acadia (just a couple wave runners), and they seem to get there. One anecdotal item, though -- they traded a Suburban in on the Acadia, hoping to improve mileage, and my brother in law reports that the difference hasn't been that great. Maybe a couple mpg, but not enough that they have been happy with the change overall, considering the trade-off in space and capability the Suburban offers. I just note that because, if you will tow a lot and might like the extra space, you might look at full-sized SUVs.
For me, the cross-over I'd look at first is the Ecoboost Expedition. Pretty nice vehicle with some get up and go! The diesel imports would be second on my list, but pricey, of course.
Good luck!
