Our 2010 Sprinter 264BHS has front and rear electric stabilizer jacks.
The pricinpal of operation is that when one of the jacks contacts the ground, it's limit switch will cut out the motor when the torque set point is reached. The opposite jack will continue to operate until it's limit swich operates.
So, if you are on uneven ground, both jacks will be able to give a firm base.
The jacks are NOT designed to "lift" the trailer, they are designed to "stabilize". That being said, I've experienced no sway or rocking whatsoever, in fact, the trailer is rock solid!
To be sure that you are getting the most of the stabilizer jacks, don't extend them too far, there jack legs cannot be straight up and down or they will never work as designed. If the reach to the ground is too high, be sure to block them first.
