I just did my first overnight smoke on my 14.5 Saturday night/Sunday. Started at 8pm, Was up to temp (225) at 9, I checked at 3am, it was at 220, woke up at 6 and it was at 190...no big deal, added a bit more charcoal, and I pulled it at 10am. It was a 9lb pork butt. Put it in a cooler with towels, went on a hike with the kids and was back home by 1:30 to eat a late lunch.
I like that it doesn't use as much charcoal as my 18 incher did, but I will say it is too small to effectively do a rack of ribs. On the other hand, it's perfect for pork butt, which is still my favorite.
