here's a little horrible...… the wind noise
might as well not put a windshield....I haven't figured out where "ALL" the noise is coming from.... but will say this...I bought a new Fleetwood,winniebago and a forestriver fr3... they all have it and there is no reason other than someone not doing there work...I fixed all of them by sealing the windshield pillers, and where the dash mounts...on the thor… I belive that part of the noise is wind under the hood going up the tubing that is not sealed off, that and who ever is the one putting the sealing foam is spending too much time on their phone and not properly doing their job...big holes in the foam sealing job that shouldn't be there
next, and this was on my 27b as well...the sliding windows don't latch and whistle like crazy....and If you are gonna tell me to keep slamming the window till it close's.... or breaks.... save it.. I found out what was wrong... and fixed it.. the swipe that they put on the bottom is too big for the side...there are some rivets on the side that push the swipe out too far...slaming the window crushes the swipe...making it work a little better.. but.. if it slams into one of the rivets the glass will shatter ,..
so the fix is to pry the swipe out with a pick and trim the two little edges off....now the window works as it should, latches with out slamming and doesn't whistle...
