Wondering if anyone is or has pulled a travel trailer with there ST. I have a tow PKG.with a class 3 hitch which is the larger .Class 3 & 4 I think are the same but anyway I would want to stay between 3 and 4,000 pounds as far as a trailer is concerned . I would be going Indiana ,Michigan maybe Ohio area no mountain driving . My trac by itself gets between 15 and 16 in the city and highway about 18 ,not great . I wondering if my mileage will stay about the same under normal conditions like NO heavy head WIND ect . But then I would not deliberately drive in bad conditions anyway . If you do or have pulled this heavy I'd appreciate your comments . Thanks . Jer.
