I've always kept the full doors on and have never done much in the rocks until our last run, at that time I was concerned about damage to the doors, not a good feeling.Well, the other side of that is doors are always in mortal danger out there. We've mentioned with very enthusiastic words that one should not go on the trail with full doors or doors that are not somewhat disposable. A few have ignored that much to our amusement. About 50 yards into the trail, doors came off and two passengers carried them down the trail the rest of the day. We got to giggle a bunch that day.
