Cake-Walk. Been doing mine since I bought it in 2007. I'm sorry but off the top of my head I don't know the sizes of the Allen wrench or socket needed.

1) open cap on valve cover

2) drain filter cap (under truck) using Allen Wrench

3) drain pan using Allen wrench

4) remove filter cap using socket

5) replace gaskets in filter cap (3) tip, drain plug, cap

6) install new filter, tighten cap

7) replace brass washer on drain plug, install drain plug

8) add 8 quarts of oil

Sketchy I know but it really is quite simple.
