Help what tongue weight F150

I have a 2014 F150 ford 4-4.
With stock tow package.

This tells us nothing about your trucks towing specs as Ford markets the 2014 F150 with;
F15o has 19 different GVWRs from 6000 on up to 8200 lbs.

but more importantly the trucks rear axle as its going to carry all the weight in the bed and some cab weight.
F150 has 5 different RAWR from 3300 up to 4800 lbs.

What is your trucks GVWR and RAWR ??

The F150 also has several engines packages so which engine do you have ??

What gear ratio does your truck have ??

The trucks specs determine how much load it can carry and how much weight it can pull.
