Unhook to level

I would be hesitant to do this. I have had the trailer raise the pin several inches above the hitch after I have disconnected it at a site that looked level. I would even venture to say that if I had left the truck hooked up, that it would have almost lifted it off the ground. That would be several thousand pounds of weight hanging on my air pin, and I would be afraid that there would be damage either to the pin, the hitch, or it would overload the front jacks. I have a Voltage 3905 with the electric jacks, and when it auto levels, it can raise the trailer quite a ways.

Just my 2 cents worth.
