I've just joined the group, pulled a twin jet ski trailer over 500miles for someone. I use my truck to make money with. Have gone from Boston to Miami at a gross weight of 7780 with a 2.3 four banger. Pulling a 8X12 flat trailer with a '12 Harley Fatboy,'01 Indian Chief full dress for both bikes, 1950 Willy's 6cyl motor & trans mounted on steel stand and a 3piece sectional sofa. Slow getting up to speed but no problems.
