That's not an uncommon occurence. Could be due to poor factory workmanship or that they just don't work that great. Below is a photo from our friends' Keystone TT. They were complaining of problems with various drawers and cabinet doors not staying closed, and in particular a door beside the bed. The two parts of the roller catch were over an inch apart. The cabinetry work in their TT was atrocious. Their dealer tried to fix some of it and just made a mess of it. I've seen Keystone TTs at our local RV show with similar obvious bad workmanship. How can the factory let this sort of stuff out the door and how can a dealer not see it or be able to repair it?? I spent a day going through our friends' TT to fix the cabinetry problems including the dinette seating that was falling apart. Their TT was only a couple of years old at that point.
We used to have various drawers and doors open while in transit - above the rear kitchen counter, lower kitchen drawers, pantry door, a door above the dinette and one of two drawers in the slide. One of the lower kitchen drawers opened once and I didn't see it and the slide tagged it but luckily only messed up the drawer slide a bit and was easy to fix. See 2nd pic.
The problem is the flimsy, el-cheapo, dime-a-dozen roller catches that are common in RVs. Some TTs bounce more than others too and rear kitchen models can be more of a problem (like us). The solution for me was Southco Grabber catches. I replaced most of the roller catches in our TT with them. They work great - everything stays shut now. They come in 3 different pull forces. They also have a microswitch model that I used for the pantry door to switch an LED strip I mounted inside it. You can buy Southco catches online (ebay, Amazon, etc.) or JR Products has similar ones that can be found at RV parts vendors. These are trickier to install because the two parts have to be fairly accurately aligned. I used painter's tape and made careful measurements and marks.
The ultimate solution for drawers is
RV "stay-close" 8400 series drawer slides from Knape & Vogt. I installed them on some drawers I built for beside the bed. They are sweet!
