I'd like to outfit one of my pickups so that I can haul and dump materials. Not sure which way to go with it. Either a dump bed insert for around 3k new 2k used, or the pickup bed conversion dump kit, around $850 new. I look at as if both serve the same purpose, the latter might be better since your not already adding several hundred pounds to the install. Both on gas mileage and hauling capacity. For those that have used either of these, whats been your experience, and what pros / cons have you run across with either of these setups?
