Hensley Arrow - Really that hard to hookup?

My Dad has a Hensley on a 32' Rockwood. (TV 2012 Ford Expedition regular wheel base.) When I have unhooked it, (which is most of the time he tows since we go together), I take the weight off of the TV, by extending the tongue jack, as you would with a traditional WD hitch system. Then loosen the spring bars...but the key is to totally loosen them...to the point they start to get tight. (In the loosening direction AND by hand at that point.) I then drop the tongue of the trailer until the point that I just start to see a slight space at the top of the 2" receiver of the truck. You could actually get a very thin feeler gauge to check it, but I find I can do it by eye. Once you see the space just begin to appear..stop and pull the TV away. I have yet to have the sudden drop that was experienced before I started using this system. Hope this helps.
