Those pads must be smooth on thew bottom??? My boxes above top and bottom have 1/4" diamond plate rubber pads. So he moved and added 3" under the tires??? Completely a waste of time.

Perfect example of why I NEVER use AUTO LEVEL. I go into manual mode every time.

Watch it again. The bottom of the jacks didn't move. The top of the jack was bending.
Knowing he war far enough out of level that he was going to raise his tires off the ground, he should have used boards to raise that side of the trailer, placed his chocks on the boards and then leveled his rig with the jacks. That way even if he still lifts some weight off of the suspension his tires will still be chocked.

Your jacks look much more substantial than his do.

I prefer to learn from others mistakes. It is cheaper than learning from my own. We are shopping for a new fifth-wheel now. And it will most likely have the 6 point leveling system. I know what I learned from that video will help me make a good decision if I am on a very unlevel site.

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?

this video doesnt make sence to me. I only have the 4 point, but once there is pressure on all 4 pads it doesnt matter how high the tires are going to come off the ground the rig isn't moving. but my rear and front jacks look substantualy beefier than thoes ones.. elecric vs hydryalic I guess. I just had to use them to lift one side of the 5th so the tires were 1" off the ground a coupel weeks ago to change a tire.

But the site was off level front to back, so when the tires were raised on the one side off the ground, the chocks were no longer holding it, that side slid forward

it had all 6 points down thats a lot more hold than the little chalks on the tires. unless the jacks are all to flimsy for the unit.

When I park our 5er at home, it is WAY more unlevel than what they showed on the video. Back then we were watching them regularly and it made me a little nervous since I had only been using mine for a year. Now into our 5th year with the 4 point electric auto level I don't even think about it. I won't have another rv without auto level.

FYI, the Ground Control 3.0 will let you go 5 degrees out of level front to back, but you HAVE to use manual control to get it to work. The system stops moving at 5 degrees. I deal with this every time we go home.
