This works, but the "easily unloads your 3000 lbs load in 30 seconds" isn't totally true when you add in needing to set up the ideal conditions needed as well the load capacity being less than you may expect. I got the 2000 lbs version when my brother ask if I'd help him get a bunch of fill dirt for his yard. It did help with emptying the truck bed more quickly, but it isn't making things as easy as if you'd added a hydraulic dump (as they may try to make you think it is).  The only real difference in this one and the 2000 is the mounting brackets, this one has steel plates with ball bearings, the 2000 was plastic.  The 2000 brackets was only 1 high max where the tarp rides and had a smooth taper up to the pipe area, this one has steel plates sticking 3 inches strait up right at the tailgate edge (which will be a "snag" for my added tarp, see below).
