The Transit has threaded holes all throughout the body for curtain airbags, rear AC mount points, tie down hooks. I used pretty much every mount available and also have lots of metal screws and brackets through the inner walls. Also, big L brackets through the floor at the base of the cabinets I learned from rebuilding Sportsmobile interiors years ago. Some don't like Sportsmobile's cabinet construction but the one thing about them is they are quiet. NO rattles or squeaks. The first van I built for myself had about 100 squeaks and rattles. I chased them down for years. You have to pay close attention to tolerances up against walls and such.
