After thinking about it, Titebond is water soluble, Gorrila glue is not. With Titebond you you can clean off the excess with a wet rag after you squeeze it with the clamps. There's no need to try to recut or trim anything, it simply pulled apart at the joint.
One thing I noticed looking at my cabinet doors. They are all put together with staples as is everything else, at least in my trailer. You have to remember that trailer building is mass production, the cheapest they can do with the cheapest components they can buy. That includes cabinetry which is most likely mass produced by their vendors also. I've noticed that the builders tool of choice seems to be a staple gun because it's fast and cheap to use. It doesn't take much to pull a staple through a piece of 1/8" Luan. My big complaint is that they also use them to build drawer supports and those usually don't hold up more than a couple of trips if you load them up with kitchen stuff. At least mine didn't. I doubt that even with the custom one-offs, they don't let an assembly sit for several hours waiting for glue to dry. It feels like I've rebuilt everything on this trailer, which makes me less than anxious to trade it in on a new one and start over with the same issues.
