yep, the quadralift will automatically level - as you already know.....so your issue is that the vehicle will fight you. The Jeep will also "cosmetically level" itself, even with the engine off - you can see this sometimes as you walk away, the compressor will start and it will make a tiny adjustment to compensate for the weight that has just left the vehicle. So you need to stop it doing that.
What worked for me was to back up to the ball, with the vehicle and the van on a level surface disable the quadralift by pushing both up and down buttons
, then load and level the combination, using Snuke's provided instructions from Hayman Reese, then start the engine and the QL will be re-enabled.
I only ever set it up properly once, then just use the same chain links after.
If you've used a WDH before on a previous vehicle you will also have some feel for the level of "snap" on the chains that gives an idea of loading.
I have a 250kg ball load and use a WDH, sometimes I find that when parked the chains aren't tight, due to the attitude of the vehicle or van, and the QL levelling. I can feel the WDH operating at times on the road though, and wouldn't be without it. Our van is about 100kg under Jeep's recommendation of using a WDH when towing 2268kg and over.
One nice aspect is that you can hook up by backing under with the camera and raising the vehicle into the coupling - impresses the onlookers too.
I also use the QL for getting some fore and aft levelling when we are parked up for the night in the shrubbery.
