I have one of the types of rail shown uppermost in the first photo screwed to the garage wall in exactly the same place with self tapping screws into pre-drilled holes, size 12 I think. The other rail is bolted through the underside of the bed at the front end of the garage.
They only support long lightweight items in the top of the garage above everything else, eg, loft ladder, kayak paddles, thin screen cover, ski poles etc.
My van is a Rapido, the inner wall ply seems quite strong, the trick is to tighten fully but definitely not to overtighten.
