I've seen folks move their rigs with slides out, in a park for a campsite move, but never on the HWY.
I suppose it happens, but with slides open there's no way to use the mirrors for lane changes or clearance navigation ... that alone kinda puts the pasky slide right square in your vision. That said, when it does happen I guess it's obvious the driver made it that far and never used the mirrors.
And yes .... I was about a block from my home and when I turned a corner I noticed a 30ft power cord following me. :)
