Horrible handling issue with major wind gusts

[SpyderLady1968]

NEED TO KNOW IF ANYONE ELSE HAS HAD OR HAVING THIS ISSUE. I've had my 2015 F3 just under a year (rode a Harley for almost 30 years before that). Yesterday while on a 400 mile road trip we started getting a LOT of wind with major gusts (the kind that can topple empty semi's). We were averaging about 75 MPH (I was riding sweep behind the group). I started having a lot of problems keeping my Spyder on the road when we got hit with these gusts. It almost felt like a rocking horse going from side to side. I finally pulled off at an exit when one of the gusts almost took me out. I left a message for a friend who just bought a 2018 F3 (this is her 3rd Spyder but first F3). She said on a recent trip she also had the same issues. I was loving my Spyder but this has got me worried. I don't want to be out on a road trip and all of a sudden get into winds and have the same problem. The bike had all recalls done before I bought it, I just had the 9,000 mile service and had a new back tire put on the day before the trip. I am so frustrated I am thinking about selling it. Any comments or suggestions?
