I installed a Southco latch on each of the two drawers I installed under the drivers side bed. Unfortunately one of them broke after a couple of trips. It may have been a fluke or the way I installed them.I replaced them with these latches https://www.amazon.com/gp/product/B0095TAXYK/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1They have worked well and provide a positive latch to prevent inadvertent opening of heavy drawers while traveling. Since they are quarter turn it is easy to visually verify latching . I have not used them yet for doors.
