Living in the desert, I have driven my '92 and'94 thru some serious winds (40+ MPH) at highway speeds and haven't had a problem, even with a 2" lift and slightly bigger tires (225-75-15). I feel the winds, but I've never felt out of control.
In my '94, I was at a dead stop and rear ended by a 2004 Grand Cherokee going about 45 mph. The Cherokee had serious damage, grill, hood, front undercarriage, and air bag deployment. It pushed me into a lifted 85 Cherokee (a Jeep sandwich!) with a steel bumper. Although totalled on paper, my little Tracker came out extremely well. What totalled the Tracker was not the rear hit, but the lifted Cherokee bent the welded front cross plate, the hood and fenders which was serious labor dollars to repair. I just needed a door for the back. My Tracker was towed to the same body shop as the 2004 Cherokee and the body man was really surprised as to the damage my Tracker "caused" on the Jeep. I think the full box frame made the difference in that accident.
