We have a rental trailer we host on Outdoorsy that requires a 2 5/16 ball size. We provide this adjustable hitch to the renter:

Note that the F-150/Raptor is a 2-inch receiver. This Fastway hitch can adjust both up or down 8-inches and includes both a 2-inch ball and a 2-5/16-inch ball.
Depending on what you're towing, you may need a sway control/load balancer. This is the case with our other trailer, for which we went with an Andersen Weight Distribution Hitch:

Between the two trailers the 22-foot rental is about 4000 lbs. The 30-foot trailer is around 6000 lbs.
The Gen 2 2020 Raptor SCREW is rated at up to 8000 lbs. However, without a weight distribution hitch it's 5000 lbs. The tongue weight is 500 lbs (no weight dist.) or 800 (with weight dist.). The SCAB has a lower rating at 5000 lbs. or 6000 lbs. respectively. You'll find that in the supplement guide, currently posted here:

Even with the weight distribution hitch, which I need to have adjusted, I get a fair amount of squat. I just installed Deaver Springs this week and haven't had a chance to connect the trailer yet to see if it helped eliminate some of the squat. Squat is bad as it reduces front tire contact for steering and throws off the trucks ability to be balanced when turning or braking.
Hope that helps.
