Try this- Go get half a yard of whatever landscape materiel is cheapest dumped in your truck bed and drive around at 65mph for 60 minutes. If you feel comfortable doing that, then overloading by 500 pounds with TT will be tolerable. I agree with those saying you'll have no problem based on power. But I don't think you'll be happy with how your exact truck will feel from the driver's seat.
Then go do the same thing with your choice of suspension upgrade and haul it like a boss all while watching your truck NOT self destruct from being a little over the ultra conservative payload rating.
