I have a 1 ton Ford Superduty with a flatbed. I've been told I should get a dump lift put on it. I checked it out and it would cost me about $2,800! I realize the obvious advantage of not having to shovel stuff out of it. I guess my question is how much money making potential is there in having a dump as compared to not having one? Is there really that much demand for hauling loads of rock, dirt, etc, that it would be worth it? Thanks.
