Well I did do it for the trail depending on how hard they are to put back on dictates if I drive to the trail door less or not. I'm usually the only one in my jeep so I'm not worried about that but I knew it would be more dangerous if I wrecked it without doors when I took them off. As far as flex goes on two tires all the doors and rear hatch open and close no problem so I don't see the doors as part of the system supplying strength in that situation.
