Well I can say I don't know what it is like to have full doors because all I ever had was half doors. I can say that I really like my half doors. I use them for arm rests in the summer, LOL. I never really wanted to take them off. No doors doesn't really thrill me that much. I like having some protection even though they are not much. That and I figure with no doors, I would probably get a whole lot more wind in the cab area. Other then that, I just think the Jeep looks good with no uppers and the top back with the half doors.
Course I'm not a heavy wheeler either. I would guess that no door would make it a lot easier to look down to see your wheels while transversing rocks and such. I am mainly city driving and occasional fire road to light off road trails.
