When I was going through Wyoming some years ago I had the same issue with crosswinds. Problem is like they said previously theres no way for wind to go through the bike and with those big fenders and trunk it just grabs it. I had upper and lower baker wings and I opened them up parallel with the bike and just loosened myself on the handlebars. My late wife and I rode through 25-45 mile an hour crosswinds for 6 hours. That was the hardest day I ever had on my trike.
