guess it would depend of the Thor coach you have, I have the Tuscany 40ax XTE, before the slides go out, the coach has to be level and I dump the air before I level the coach, the key has to be on (not engine running) in order for me to extend or retract the slide. I too hold in the button for 3-4 secs after the slides are in or out. In the control area above the passenger, it clearly states that the coach must be level before slides can be extended.
I have experienced twisting of the full wall slide, in order to correct that, I was told by Thor to extend 4 inches, retract and to do that a couple of times to correct the twist.
