My standard technique for mounting something that is too heavy or has too much leverage on a surface is to use long bolts that go completely through the soft surface and lag into something substantial. I cut a piece of pipe that is exactly the thickness of the soft surface, threading the screws through the pipe. This creates a solid platform to mount my gadget without placing any stress on the soft surface. Take care to seal against weather if necessary.
This is the way to do this. Liberal use of clear caulk on the outside of the pipe and inside as well will seal against moisture. You have to seal penetrations made in dryvit, or you open your self up to all kinds of issues with moisture getting in and the damage it does.
