I built an aluminum case the width of the bumpers in the front of the camper to fit between camper and front of bed. In that locking case fits shower curtain, shovel, axe, biotite stove/ BBQ, extra gasoline, LP wand for camp hooking up stove and lantern outside, awning crank, leveling blocks, bug net for awning and a variety of emergency repair items that I do not use often on the bottom. Unless you shorten front camper bumpers this space is useless so provides a nice unused space to store all of these items. Do not need to attach to truck bed because there is not enough room with camper overhang for anyone to lift the box and steal it. I have surrounded it with weatherstripping so that it does not wear on truck or camper when traveling, It does add a little to complication for loading and unloading camper from truck but well worth it for accessory items.
