Easiest cheapest way to make dump

[SuperDutyScaler]

Im at the final steps on my F550 build and I'm trying to get the dump bed completed. Was looking at the lesu lifting mechanism because it resembles the setup thats on the F550 dump truck i have at work. Is there any other wAys that are cheaper or better? $65 for the lesu alone then i need a motor and esc to run the dump and a gear reduction for the motor and ill have to mock up some type of mount to hold the motor to the chassis and then hope it all fits behind the a single cab and in between the frame rails
