I have a Delta low profile box that i picked up from the local Schucks for ~$150. Aluminum diamond plate, full width lid, dual handles. I really like it.

As far as tow points, if you have a trailer hitch receiver in the rear you can buy an adapter that goes in the trailer hitch receiver and has a D-Ring shackle in it. This is the strongest rear tow point setup w/o installing custom bumpers.

Up front, you can get tow hooks from 4 Wheel Parts that will install in the frame up front. They replace the cheapy factory tie down brackets for when the truck is shipped and use the same hardware.
