You really don't understand the purpose of the WDH.
A WDH has nothing to do with your truck and everything to do with the load carrying capacity of your receiver. Sound like you need to educate yourself on the subject, I suggest going to the manufacturer of your receiver and get the numbers. Then compare to the tongue weight of your trailer.
Most likely you have the standard class III hitch; 5K lbs weight carrying and 10K lbs weight dist. Tongue weight is 500 lbs weight carrying and 1000 lbs weight dist.
