Slide design by Grand Design

After owning several types of RV's I probably wouldn't have thought to go over this on a PDI either. Sure I went over how the slides work, but it may not have occurred to the OP that there is ever a need to open just one slide or any combination. Sounds like the OP found out what he was looking for and that's great. But I know for sure that buying a house - heck designing and building my own, as well as buying cars and RV's, I've always learned quite a few things months after ownership. You just aren't going to know, or even know to ask everything on PDI day. If that were the case this form wouldn't even exist.
