Most of the V6 Compact CUV are rated 3500, 2.0 ecoboost is as well. This would be the Equinox, Outlander GT, Escape and Rav4 class.

Assuming your on a college budget, I'd be looking for a 200x Equinox 3400 v6. An Mitsubishi Endeavor from back then would be interesting as well, MPG not so good and timing belt engine. Last of the Montero/Montero Sports(5000 rating) could do it on a budget, what you save on purchase price you can afford to spend on gas & timing belt.
