Welcome to the forum!
We had the same issue with the pantry door (caught it on the slide more than once before I started remembering to check it). Added a second latch to the door last fall and it seems to have fixed the issue.
One of our kitchen drawers will slide partially open occasionally, but other than that no problems with them. When they do open, it's generally after we've been over some particularly rough road - not unusual in MA.
The wardrobe door is a poor design, but we've made it work.
Overall we are very happy with the TT, and the pantry door and kitchen drawer should be quick and easy fixes.
