Towing questions

[Overdriven]

I don’t know much about towing but at work I have been tasked with coming up with a layout for a trailer. Currently looking at a bumper pull flatbed equipment trailer, double axle, 5,200lb each axle, 12-14 foot bed, gvwr of trailer is just shy of 10,000. Actual trailer weight is 2,600lb and will be putting 6,000lbs in it. My best calculations put tongue weight around 1,000lbs unless we go to 16 foot trailer which should drop tongue weight to around 750lbs.

My two main questions are more about the vehicle needed to tow. Currently
have a 2009 F150 FX4 available which google says has a tow rating of 8,400-11,000lbs. It has a hitch but haven’t checked class yet, 2” receiver is all I know. My concerns are tongue weight and the fact the loaded trailer will weigh more than the truck. Gooseneck isn’t an option. Aim your criticism and advice here please.
