I don't have any idea as to the units that are presently on the market, but I am familiar with the units that were available 30 years ago. I used to sell them when I was involved in a truck body business. They are good, but they do lift the height of the bed and it looks strange to see a pick up box that is higher than it is supposed to be. I have also seen some that mount a box in the pick up bed for dumping. Those are more practical, but have their limitations. You have to realize that all that extra steel and hydraulics takes away from the payload that you can carry. If you are using it for disposal of trash or leaves, then that shouldn't matter. If you want to pick up mulch and top soil, you are going to be overweight quickly. Personally, I think that a dump trailer is a lot more practical for most uses. I have a F250 with a dump body on it, and I rarely use the truck because a dump body isn't suitable for most uses that I would want a pick up truck for. It is a 1979 and it has under 30K miles on it as a result. I use it primarily for snow plowing. Junk.......
