I'm from the 'old school' of offroading where I tend to hang my head out the driver's side window when driving, to see where the front-left tire is tracking. The tube doors help a great deal in visiblity, allowing me to see what I'm about to drive over or through much better. It also gets a bit warm here in South Texas most of the year, and removing the doors helps cool the interior down a bit, even with the hardtop removed. The one downside I see to no doors is the cab will flex alot more, so that's why my tube doors are latched to the striker. I also have the cage tied into the B-pillars to keep them from cracking. The body tub flexes quite a bit over uneven ground, and will crack behind the rain gutters and other seams. JSM84
