no weight in the bed? not a prayer, might as well save your money for tow trucks, because just 4wd will lull you into a false sense of security right up to the spot where you run off the road/hit someone/something. even a jeep CJ can use a bit. used to lug a few bags of mixed sand/gravel in mine for ballast & worst case traction aid. carried a shovel, come-along, and an axe too.Even a 4x4 truck can be useless in the winter without weight.
