Yes, what hitch, and how far from the hitches pin center to back of cab? I have towed 2 different FWs with Ford 6'9" beds without issue. The first FW did not have a rounded front like my current one. The one now, with EZ turn does not even come close in fairly tight turns. My B&W hitch pin center is about 40.5 inches from back of cab.
A few inches forward makes a big difference, but I think I could go to 38 inches from cab, to pin center of hitch, and still have no issue. My Ford rear axle center to cab is 41 inches.
