I always do a walk around the rig before getting under way from home, campground, fuel stop, rest area stops, etc. I check for open windows, open utility connections, unlocked doors and storage compartments, hitch still set up as should be, umbililical cord still hooked up, low tires, etc. I have added the windows to that list when we had our old TT when DS didn't latch the egress window by his bunk and it was flapping for a few miles before I caught it in the mirror.
With kids around you never know what can happen, but would never trade them for anything.
