I ride interstate quite a bit and encounter semi trucks regularly. I ride an f3s with all stock suspension and find the bike little bothered by semi wind. Your body feels the buffeting and if you try to overgrip you will cause the bike to sway off course: try to keep the handlebars pointed straight down the road. Your machine does not need additional input to stay on line. I have driven over 70,000 miles on a gs and f3 and never found a need to change out stock sway bars or shocks. I corner well above posted speed advisories (50 in a 30 posted, for example) and faster than most riding companions. A lot of what you read is from newbies who haven't learned to ride properly.
