Jeep Gladiator Under Seat Storage BoxStorage space is very limited in any Jeep, but especially so in the Gladiator. Under the backseat is the only large volume of storage area available. Some Gladiator models come from the factory with a plastic tub that encloses the area under the back seat, but the problem is that the plastic tub has to be bulky in order to give it some rigidity, which wastes valuable space.
