How easy is it to....
 

unlift a truck?? lol. Im thinking I want to take the lift off my truck to maybe help it sell easier...is it worth it or should I not bother?

i would say you could, but you will need diff shocks and such. i would imagine the only thing missing is the stops on the front frame rails. the rear should be a simple task.
look over the lift instructions and see what you removed.
gut reaction is yes.
