I personally wouldn’t do it with one of my big slides out, especially if it’s a Schwintek. I have moved a few feet with the small bedroom slide out and had no issues. I don’t make a habit of it though.

It takes about 15 seconds to retract the slide on my 29RKS. I would not risk possible damage to the slide by moving the trailer with slide out. Could it cause problems, I don't know. (15 seconds to retract the slide.......)
Slides are temperamental even in a level state, I personally would retract the slide. Coming on/off tire leveling blocks could create a sudden jerking motion of the extended slide.
Has anyone readjusted you level with slid out. Maybe just driving off plastic blocks to add additional plastic blocks.
I did it last time out. I know it's not recommended, but I wanted to add another inch of block, and didn't want to run the slide all the way back in, so I carefully rolled off and on. Had no issues.
