How are your solar panels mounted?

I have 8 brackets on each panel that hold to the panel with 1/4" stainless screws/knobs. Since each panel can be raised in any of the 4 primary directions, I've adjusted the brace lengths for summer and winter in the southern part of the US and the same for the northern part of the US. Not exactly optimum for each panel, but by using approximations I'm probably pulling at least 90% out of each panel. Of course this means I have to be aware of the orientation of the bus and need to park it as close to the cardinal headings as possible. Since we boondock a lot and don't put the panels up unless we'll be in one place for 3-4 days or more this method works well for us.
