I'll put some pictures up of my DIY solar module mount I made for the roof of my TT. It actually tilts fourways. I would suggest that anyone wanting a mount with tilt to only make it two way tilt. The use of the other two directions isn't (or hasn't yet) been worth the effort. Anyway, it is all built from new aluminum stock so may give you some ideas about fabrication.

If your objective is to use the modules as portables, I would suggest to beef up the frame where your tilt strut attaches and use a good threaded fastener with a handle so the struts can be locked into position. Short of making a base and securing the base down to endure severe wind, a couple of struts/module is about all you need.
