On our 38FDDS, I've adjusted the latch plates several times and seem to have finally hit upon the proper engagement. One of the short doors under the LR slide still occasionally is open after a run, so I just open and slam it shut as a matter of course. Just haven't got time recently to play with the latch plates. Crawling inside to view the "engagement" of the latches is difficult at best - hard to view w/o a flashlight and inspection mirror.
