Don't want to get in a back and forth on this point of a pull test. But one thing I will have to disagree on when you compare a pull tests between a commercial tractor/trailer and a RV fifth wheel. It don't take much throttle to get out from under a FW if your jaws aren't locked.
My buddy (triple axle toy hauler) had to have a fellow camper move his fiver for him because my buddy's truck was broke down. The guy hooks up and gets it moved to a spot in the CG. The guy gets out and before my buddy could lower his front legs the guy pulls his lever on the hitch. The fiver immediately rolls back off the hitch and slams onto the guy's truck's bedrails!
Now that didn't take much throttle with about 4,000 pounds of pin weight now did it.
Why weren't the wheels chocked, especially on a slope?
They really don't unhook that easily except in those situations.
I really do have experience here, so feel free to make these statements and ask questions. The visual inspection really is the most important test when hooking up.
Just for the record, I did do a pull test with my 5er. A REAL pull test, I backed under until the jaws locked, lifted the legs very slightly (1/4 inch) unlocked the jaws and drove out.
I did it on level ground.
