I'd trust 2-3k behind any of the mid-sized trucks assuming they weren't bare-bones 4cyl models. When I had my Frontier it would pull/stop 2-3k lb pop-up camper with zero issues. That said, I don't think I'd go beyond the 2-3k lb, small camper/utility trailer. Towing that same load with my F-150 is a whole different experience, you literally don't even know it's there.
