How to create simple truss with adjustable slope?

[Anonymous]

Hi, I'm an experienced Revit user but I have very little experience with trusses. I've attached a sketch of a truss family that I'd like to create, but I'm not sure how. It would be simple 3 panel W-Truss, but with an adjustable low and high point (being able to simply attach it to my roof and automatically match the slope would be incredible!) 

Any help or suggestions? Thanks!

See screencast for steps.   Family file is attached for reference but it is dead simple to create from scratch.
