I have been struggling to find a complete course ... like an Administration course or a Developer course for trouble shooting Humvees. I am also looking for a way to find a great type of online course to train me to know the tricks and treats of the newest Humvees.

 

Not aware of one. Might try Flash Off-Road Photography, Hummer Accessories, Hummer Maintenance, Modifications and Tech info. Chuck has a pretty good website for civilian Hummers. Also look at the Hummer Knowledge Base.
