I always unhitch. I got extremely sick camping one night and had to wake up the man to take my son to our friends TT and me to the ER. This was about 3 am, so he was sound asleep. If I would have had to get him up and him have unhitch the trailer, get the kid to the our friends, and get me to the ER in a strange town, he would have not been very happy and then I would have been mad and sick.
It only takes a few minutes to unhitch when you are unloading, but in the middle of the night, when you are half asleep it takes longer.
