We have a 2012 Monaco Knight 36' PFT, love the coach but recently developed a front wind noise above 35mph. I have taped the windshield  360 degree and also the weep holes on both driver window and entry door. This seems to have helped a small amount but still have original noise. (Very annoying).  Just pulled out generator and see where a lot of lines pass thru firewall. Don't know where to start. Help please
