Tilt truck bed on F150 and F250

There have been several times where I have used my F-150 to get a load of Top soil or mulch and I have wished that the bed of my truck would raise up and tilt. I never liked the Idea of double handling of material. I know that there is an after-market kit you can get to convert it to a tilt bed but that can get really expensive but if it came standard or as an option I for one would purchase one.
