We have the 2012 29-5E, similar floor plan, just a couple of feet longer.
The only time I had a problem with the drawers was when I had pots and pans in the lower big drawer - it was too much weight for that drawer latch. I installed a childproof latch and rearranged storage and have not had a problem since.
I slap all doors and drawers as part of the rig for tow preparation, and before I open the slide I check the pantry door to be sure it has not bounced open. Again, redistributing how things were stored fixed the issue so far (canned goods are now on the bottom shelf). Forgot to check one time and popped the trim off the slide. :o
