I'd say hard no on an F150 unless you have the rare HDPP version.
Payload is a red herring - basically a suggestion from OEM's to help you keep your headlights from pointing at the sky. All sorts of assumptions on load distribution with this number. Example - my F350 has nearly 4000lb payload, but when I put my old toyhauler's 1900lbs of hitch weight without weight distribution, the suspension was nearly on the bump stops. 2,000lbs in the bed distributed? Barely even notice.
Your real safety/legal number is your Rear Axle Weight Rating. These are usually limited to match the wheels and tires respective weight ratings. Are you running E rated tires? What are your wheel weight ratings?
Beyond this, I'm sure you have all sorts of other stuff in the truck like fuel and camping supplies, crap in the cab. Go find a CAT scale and weigh your axles with you and the wife and 570 loaded except the trailer.
I've wrestled with this issue myself, and was OK with my Wolverine X4, but now with my Ranger I'm a few hundred pounds over RAWR, yet within my wheels/tires which are the limiting factor.
