Lippert six point levelling jacks
I have Lippert's six point levelling jacks and i'm wondering how "off level" can the bases/system handle/ In my lot in florida, the concrete area is roughly 3" lower from the right to left wheels and ...

I watched the KYD video and still don't understand. Obviously they believed that the rig had shifted and bent the jack (I couldn't see that). After having tech's review things everything was OK. Was there a real problem?
Fundamentally, can someone explain the hydraulic leveling operation to help me understand the issue. I have autoleveled hundreds of times over the last 4yrs with our VL, probably ~20% of the time having some of the wheels off the ground. I've also lifted some, or all, of the wheels off the ground changing tires etc. I do have MORryde IS so I'm not concerned about an equilizer inverting.
If I'm correct, the Lippert 6pt leveling first tries to level front-back using just the front jacks. Then it levels side-side using the rear jacks. My assumption is that the front two jacks are always hydraulically tied together such that fluid flows between them to equilize pressure; similarly the back two right jacks are tied together, and the back two left jacks are tied together. If this is true, when the right rears are lifting trying to achieve left/right leveling fluid will be flowing between the two front jacks to keep pressure on each side equal. Once sufficient weight has been loaded onto the jacks I don't understand why any wheel chocks would matter any longer. Could someone help me understand why there's a problem?
FWIW - I always chock to take the lateral load off of the front jacks when hitching/unhitching, similarly prevents too much lateral load on the front jacks *before* the rear jacks take up significant loading. To repeat my question though, once the jacks have taken up the load why does it matter how level or unlevel the site is?
