>>Anyone know much about pickup truck boxes and chests? These look ok, but how do they attach? Do they attach? Any recommendations on brands? Trying to keep it around $300 and would consider used ones, though I haven't seen many of those. This will be used mostly to keep our golf clubs in.

>From what I've heard, Delta is a good brand, and you want to get an aluminum box. That looks like a good one.

Looks like Sears has them even cheaper too. There are rings on either side of the truck bed near the cab. Would I somehow attached the end handles of the box to those? Just curious what keeps it from sliding around.
