The main number you want to look at is what your truck will carry not what it will pull. What you want to look at is total GVWR. I think the normal tong weight is between 11 and 15% so if your trailer is going to weigh lets say 7000 lbs then your tong weight or the weight that you will be putting in your truck would be around 1050lbs. Then you add the gear in the truck the people in the truck the trailer hitch the and that will give you the weight your truck is carrying. If its below the GVW of the truck your good to go. If not then you are over loaded.
