I have a 95 Dodge 2500 diesel 2wd and need a better way of handling grass/leaves than transferring stuff to my dump trailer every day. Has anyone converted their pickup into a dump truck by installing a hoist kit to raise/dump the factory cargo box? Northern tool sells a kit for $940, which is less than half of what a dump insert costs. It is rated to lift 4000 lbs. and to me seems better than an insert because it only adds 200 pounds to the truck. Is there some disadvantage I'm not seeing? whatya think ?
