I just towed my (new to me) boat 40 miles yesterday. It is every bit of 3500 lbs on the trailer. No brakes (seller told me the trailer had them, liar). The truck took forever to get to 60 and was not even reasonable for stopping distances. I will not be towing it again with my 5-speed Frontier if I can help it. I can't believe that Nissan says the 4-bangers have the same towing capacity for the 5-speed.
