mstmoritz, I have the same problems as you. I dont buy the level issues. It doesnt take a rocket scientist to figure out the hydraulics are not even. On mine the door side hydraulic moves before the other as well. I notice the higher I raise mine the more unlevel it gets. That shows something is up. Because if unlevel 1/4" at one height it should be the same 1/4" 4 inches higher. Anyway not hyjacking your thread just wanted to let you know that you werent the only one noticing the hydraulics arent raising together.

The hydraulic jacks come down, sometimes together, sometimes one before the other. The jack with the least resistance (internal, seals etc) will move first until it hits the ground. Then the other jack will follow until it hits the ground. Once pressure on both jacks equalize they will continue extending equally.
If, after you are done raising the front and for some reason that jacks are not equal (don't understand how you are measuring this), two things come to mind:
- you have two different lift cylinder pistons. Hydraulic cylinders of different diameters will move different amounts for the same amount of pressure.
- You have raised the coach to the max cylinder height. In this case, different mounting heights of the cylinders will give you different overall height.
My trailer raises equally all the time. But if I run the jacks to the stops, one side will continue raising about another inch.
This is either because the 2 jacks have different internal stops or piston length (not likely) or because the mounting brackets are welded on about an inch off between the 2 side (most likely).
Either way, hydraulic jacks and leveling are one of the best things to come to the trailer world.
