I do not have the automatic system. When I have parked I press power, start and all extend. The front two drop down until each touch ground, then the rear extend the same way. I then check the level and adjust as needed without getting out of the seat. The fully automatic system completely adjust its self. It can need to be reprogramed at times. I have also heard that when it levels its self some times the tire could be lifted off the ground. I do not want that. The other reason is the auto system cost $1,000.00+ more.
I had a smaller unit like yours and had only one slide. I put the manual hand crank down jacks like you see on many trailers. They worked pretty good and at least they stabilized the unit from rocking. You are only into those for less than $200.00. You might not need to spend the money on a Big Foot System.
