I have solidworks 2015 but want to save so something with 2013 can view it, is this possible? Or what is the best form of 'dumb solid' that they can view?
It is not possible to save as an earlier version of SW. A good neutral solution may be step, which has worked quite well for us. This will not be viewable in edrawings. For that you may use stl instead.
you can't save as native SW file - too much difference between versions.
but you can alwasys save as many of other formats (igs, step, etc)
