So, I just bought one of these last month, and had my first tow with it. Is it the best lightweight tow vehicle ever? Maybe! I did about 400 miles total, all interstate. Camper is a Rockwood 2280BHESP, which is about 2600lbs dry. I had it loaded, full, and a heavy cooler and supplies in the bed. If I had to make a best guess, the trailer was a hair over 3000lbs, and the truck was loaded nearly to capacity with 4 people, the tongue weight, and the load in the bed. I kept cruise on between 68-75. Truck ran about 2K RPMs in 6th gear. It never downshifted, not one single time on a hill or otherwise. It would climb a steep bridge in 6th gear and never struggle. I was completely amazed by the low end torque. The built in brake controller, and exhaust brake work brilliantly. Zero drama, even when descending. The best part? The truck returned an average of 22mpg while towing!
