I did that once on my previous TT. Pull away from home, got down the road about a half mile and saw it when doing a turn. Fortunately, my black cord for the camper was plugged into a lightweight construction type extension cord (just enough to keep lights running). When I pulled away, the camper pig tail unhooked from the orange cord, so nothing was hurt, except the orange cord pins, plugged into the wall were bent up pretty good!
Never did THAT again! Live and learn!
