As I'm a newcomer I'm just now reading this TR, but I have to say it's a great read and the photos are great as well. I assume the 3 point turns you mentioned being required in the Maze would preclude towing a small trailer? I have an AT Chaser that I tow behind my FJ and have started planning for my annual spring trip to southern Utah next year. My goal is to do as much of my camping as I can in outlying areas like you did.
Great report and thanks for letting me vicariously tag along. ;)
