BnD: "We have the Copper Spur UL 4...Only issue we have is the door configuration in that they zip across the top down the sides with the open door laying on the ground. I prefer D type doors so I'm not climbing across the tent door every time I get in/out of the tent. (no, we do not ever wear shoes in the tent) Minor complaint but, I do think it will shorten the life of the tent due to wear and tear on the tent door. My .02"
BA rectified this design flaw (I completely agree with your assessment) with last year's model. It is now a D-shaped door.
