One question, before lowering box, did you move forward first? Nice video, thanks.
2) Raised the trailer to the 3rd stage or noticing product flowing out by looking into the side mirror. Usually the 3rd stage starts the movement of product.
3) Stop the upward movement (once you see flowing of product falling to the ground) and flip your brakes by setting your tractor brakes then releasing the trailer brakes.
4) Usually I would move it one stage up so the center of gravity moves closer to the ground instead of being in the middle of the trailer. But if in doubt, go up slow. No rule says you must dump it fast. As the trailer goes up the trailer tires will move forward while the truck remains stationary.
5) Once you are as high as possible, either all your product is out or you must move forward about 4-5 feet. In this case, release your brakes and move forward slowly. Nothing will cause you to tip since you alread observed the trailers path for that short distance. (such as dips or obstacles. 4" or greater difference from left OR right side in the path may...will give you a sphincter check and you might have a problem getting off your seat. (jk?)
6) Once you see no more product falling out (the dust will stop or you will see light between your axle), set your trailer brakes, leaving your tractor released. Lower your bed. (if you lower your bed with the trailer brakes release, your trailer WILL ride up your newly dumped pile and you WILL tip over. So remember to set that trailer brake when lowering the bed)
Noteworthy advice: if you move forward for any reason while up in the air, and you step on the brakes. IF you DON'T have your brakes adjusted (both sides of that trailer axle that remains on the ground) properly and only one side is applied while the other side is not, the torque will tip you over. That is because while the trailer is up high. The brakes on that one side, that is applied, is acting like a fulcrum or pivot point and the top of your trailer will sway towards that applied brake side. So don't neglect your pre-trip brake check.
Hope that helps. It is a lot of fun doing this job once you pay attention to how your truck operates. No one knows your truck. Only you do. Don't neglect the dangers associated with this job. Ted.
