Toots, check this out. This is a steel tool box made by delta. It's pretty small. You mount a bracket to the floor of truck bed, install the on the bracket and twist the latches INSIDE the box. Then lock the box. It's not real secure unless you added hasps and padlocks on both sides so you wouldn't want to put anything really valuable in it. Also you could have it black spray on bedliner to make it black. The only problem would be the bracket is about an inch tall - you would have to have some pretty thick bedding not to feel it.
