In my 2001 you cannot extend the slide without "tricking" the HWH system into thinking the jacks are down. You do this by first performing a "level" operation or manually deploying the jacks and cancelling it before it is complete (this is why you saw slides out and jacks up). Since it is a safety issue (in my mind) if you are able to drive off with jacks down, I am wondering if HWH changed their software to disable moving with jacks down, rather than just sound and alarm. If they did, it seems logical that the same status would prevent the slides from operating. Even if they didn't, it still seems logical that a jacks down status or drive status would prevent a slide from operating. Which leads back to my previous post regarding the connectors/wires. Just something to consider.
