In my opinion, it is certainly nice to have but I do not have an awning on my current TC. Had one on a previous pop-up and there were times when in very open areas with sun beating down that I enjoyed. Most of my camping is done in fall (hunting) and winter (ski-camping) and it is not missed.
One item to note: mine is for sale and have had comments from many a potential buyer that passed on it because it did not have an awning. Getting an awning as an option might affect resale desirability.
