Please don't change the subject as the thread continues. Here's the subject I am talking about: Flipping the hitch-nothing else, not repositioning the tractor, adding safety chains, etc.. The hitch has about a 5" drop to it. As you can see the hitch is flipped into the up position, creating more clearance for the hitch. Flipping it down, with the trucks excessive sagging condition would make the hitch too close to the ground. Whether it helps level the trailer won't overcome the drastic change in the hitch position.
"If done properly" is your way of changing the subject. Sure if a lot of things were changed (done properly) that set up could be made safe, but simply turning the hitch over only makes the hitch too close to the pavement for safety.
