My (new-to-me) coach has only one of the Girard roof awnings on the curb side.  I'd like to add a second one aft of it so I have full coverage on the side.  Newell wants $10,600 for this second awning.  I am thinking about sending this work elsewhere to save some dough, but I am encountering some wariness about penetrating the roof to secure the big brackets that hold these things on as well as run the wiring.  

So, this makes me wonder...  what's the roof like up there anyway?  Any place to avoid in terms of adding holes?  Obviously, we want to put in as few as possible!

Thanks,

Ben
