The yellow sticker says your truck is not designed to carry more than 1380 pounds. Period. Past that, you risk overloading the suspension, possibly overloading frame components, exceeding braking capabilities, possibly overloading the tires, or axles. In short, it is NOT suggested. Will the truck self destruct if you are 10 pounds over? Heavens NO! 100 pounds over - same answer. 100 pounds over is only 7% over. 500 pounds is a whopping 36% overweight.
The weight distribution hitch DOES NOT remove weight from the truck - or not very much. As a rough estimate, if you have a 1000 lb hitch wt without a WD hitch, all of which is carried on the back bumper, it may add 1200 lb to the rear axle and take 200 lbs off the front axle (leverage). A WD hitch will redistribute that weight, maybe add 600 lbs to the rear axle, 300 lbs to the front axle and 100 lbs back on the TT axle. The truck still carries almost all the weight.
As RVRAC said, you need more truck.
Since this is your daily driver, a different ? ton MAY meet your needs.
Ford offers a Heavy Duty Payload package on the F150 which includes 3.73 rear end, heavier rear axle, heavier springs, aux transmission cooler and bigger tires. With any truck (or car) more options add weight, which reduces Payload. Likewise for bigger cabs. Go with the smallest cab and fewest options you will feel comfortable with. Add HD Payload pkg and see where you land. Note, this may be very hard to find on a lot somewhere, and that makes it hard to see the yellow placard.
