This thread is going sideways somewhat, but, its not like that slide is a teeter-totter. There are various designs of slide mechanisms, some carry weight, some just push and pull. When the slide is full IN, the outer wall is pulled up tight on the outside of the trailer and if you apply weight to the slide, the bottom stays put, and the top of the wall keeps it from tilting in. Older slides somewhat depended on the carpet under them to support them, with the move away from carpet, I'm not sure how its done now. In any case, saying you cannot use a slide when it is retracted is, well, outlandish.e
I have a friend that has a slide that is the full depth of the dinette. When it is extended, none of the slide is inside the trailer, none at all, so is he supposed to deploy it half way?
Me, I don't like slides, had one in the motor home, hopefully will not have one again in anything.
