Slide out question

Thank you all. I think I'll always slide out all the way.

For the most part no, it's bad and will indeed hurt something. With a regular rack and pinion type slide, stepping on the cantilevered plywood in front can break the plastic guide across the front (I did it).
If you have a Schwintek system, it will foul up the timing of the motors and computer big time. Then it may not close or open completely until it is re-timemd.

If my bedroom slide is all the way in the bed goes under the cabinet slightly. If I need to sleep in the bed I have moved the slide out a foot or so and slept there. Once it was because of the parking spot I was in. I frequently slide it out a foot to access drawers to pack,unpack. The front slide ,not so much. The front slide drops a bit once it starts to extend, I see no reason to avoid stepping on it when part way extended, it's a solid structure.

Depends on why. If you only need it out a little to be able to get by to access the fridge or bathroom, no problem. But I would not walk on it.

Depends if it rains or not. In some MH models the slide will leak if not fully extended.

Won't hurt anything, what would be the reason not to put it out all the way?

Not good, due to the seals that only work when the slide is fully extended.
