4700 lbs is fine. I think they top out around 6000 lbs. It's not the towing as much as braking, adjust your distance accordingly. I tow a 5500 lbs boat/trailer 160mi each way 2-3 times a year. It's not a real problem. Mileage is horrible, and it's slow going, but I do just fine. With the short wheelbase of the 2dr, expect to get pushed around a little depending on the length of your trailer. My trailer setup is about 8 feet longer than they truck itself...ugh! Do yourself a favor and adjust the load so the tongue weight is 150-250(There is a ratio for this perfect weight, but I found this has always worked for me). It can get bouncy above 250. I also only tow in Drive "D". No O/D (Overdrive). If you drive in O/D, that amount of weight will cook the tranny fluid in short order on the highway, even with a tranny cooler.
