1/2 Ton Limit
Current set-up 2018 F150 Screw 4x4 3.5EB (1907 lb payload). Husky Centerline TS Hitch Jayco 22FB (6000 GCWR). No real stability issues. I usually have 1500+ lb left for tongue weight (I'm solo)...

Getting back to the title 1/2 ton limit. With your F150 and it's 1907 lb payload the F150 forum consensus would put it's limits at 30' and under with a top end of 8000lb GVRW. Some on the F150 forum have HDPP 150's and they successfully tow over 30' and a 9000 GVWR. At 15% tongue weight that 8000 would be 1200 so you've got plenty of payload left over.
