I'm assuming RT41 no longer has a problem.
My jacks will extend/retract with slides in or out.
Jacks will retract with engine running. Have not tried to extend with engine running.
My engine will start with slides in/out.
Slides will NOT move with engine running.
Initially I really had a problem with running slides out prior to leveling with the jacks. After the kitchen slide jammed a couple times going out with the jacks down and went out smoothly with jacks retracted it became a lot easier to follow instructions!
