Well, V4 can be weightmapped, but EClark is correct, she is not officially available as a weightmapped item. 

At one time, V4 base was available for free but not anymore.  If your Poser supports weightmapping (Poser 9, Poser 10, PP2012, PP2014) I would pick up Dawn while she is still free.  These opportunities don't come along often; best to act before the offer disappear.
