Not enough payload. The 13,300 number is meaningless until you have satisfied the payload. If the pin weight is 2080, plus you and other people and fuel and cargo.......is about 2,400? 2,800? 3,000? I dunno.......I will strongly guess that is way above your carrying capacity. Until that number is satisfied, how much it'll pull is immaterial.
