Will probably end up fabbing one up. A friend and I did some fiberglass over wood deckwork on his boat and we made a pretty ridgid fishing deck. Might be able to do something similar, but have it be static (unhinged) as well as flush mounted. That way I can do an up to the rail bedliner and maybe fill my stake pockets in the bed rails. Options options. Don't use the bed too much for bulky stuff, but I want to keep a matching spare in the bed as well as a duffle full of roadside assist stuff. I'll keep searchin' and thinkin'. An afterthought, maybe bedlinering the cover (aka reinforced piece of plywood, mdf, or whatever) as a means to protect the top surface of the wood? Would countersink mounting bolts and hide them with the bedliner coating and do wingnuts underneath or nylon threaded nuts so I can remove it whenever I need to. Huh. Thanks guys!
