FlareScrew

I am trying to figure out an accurate and safe amount of weight that I can load into my bed and tow on a 6' X 12' flat open utility trailer. I buy and sell gym equipment on the side and purchased an entire gym from a school. I have a 24' box truck that will be assisting with this but I am also paying an arm and a leg for the box truck so I want to do the majority of the moving of plates, dumbbells, and smaller things on my own. I have an 07 XLT Flareside Screw with the 5.4. I have over 10,000 pounds of weights I need to move and want to get it in as little trips as possible without hurting my truck. Any advice would be greatly appreciated

1000 LBS in bed and what is your trailer rated at

Thank you. I am borrowing the trailer and don't have it in my possession yet. I will have to ask the owner what the capacity is then.
