IF the initial price is affordable, go with an RKI brand tool box. They warranty these things FOREVER. The one in my fathers truck is about 18 years old. It has been through 9 trucks and the hinges finally pilled away from the box itself. (Keep in mind we put about 50K miles a year on trucks.) He went to RKI to buy the hinges, and replace them himself. They took his keys and asked if he had an extra hour or so. Two hours later, his box had a new hinge, lifts, locks and seals. They handed him a certificate to an off site powder coater as their booth was not set for custom colors and charged him. . . $0.00.

If you are looking for Auxiliary fuel and tool storage PM me, and I know of some folks to talk to.
