You can use the 6.2 diesel for towing, but you may not get the expected speed to find the 6.5 and stuff. So, it would be better if you didn’t compare the 6.2 with others who are happy enough with the slow towing speed. The main feature of the 6.2 is that it has good fuel efficiency. You will probably get better mileage, but it may not satisfy your need for a fast tow. They are suitable for local services.
