Our Monty came with those latches, but they don't always hold. Going around corners at highway speed often sent a heavier galley drawer slamming out, dislodging my startled wife from the co-pilot's seat as well as screws that mount the slide mechanisms. I found that there are two versions, the weaker of which is on the drawers and cabinets. When they broke I replaced them only to suffer the same fate again. If you go to them, try to use the heavier duty one. If memory serves correctly, Beaver used the HD on the rear closet doors because of their weight. The HD latches don't crack around the thicker screw plate like the lighter duty ones. I believe the HD is rated "10 lb." vs the other at "5 lb.".
Not sure why he put the rear TV on a swing-out. It's mounting panel blocks access to a potential storage pocket. On ours, the TV cabinet upgrade consisted of putting the TV on a cabinet door, so with shelves we still had the available storage behind.
Wish we had the slide out roof drift that some rigs had; those Carefree slide out covers can be a pain when the wind kicks up. I have to bring in at least the windward slides in order to sleep at night on the Oregon Coast in winter.
