suspicious as it looks...thats along distance traveled from his pit stall with a unit not Hooked!!...only the Driver would be awhere of his Veh. condition after doin his walk around/Pre-Trip req. DOT inspection!!...If a good distance was made b4 the Drop??..it could also have been possible from a "FALSE HOOK"!!...just say'n....had this same thing happen to me in the yard!!...one way to avoid a drop, is always to do a Rev. or back-up tug test..Plus a visual to see if the collar is completely locked round the PIN!!...this will insure this from not happening again!!...baring any damage to unit/contents,prob.damaged PigTail (elect cord)no lites lit on Trl,connecting (red/blue)coiled air hose's!!....sorry ta hear it tho!!.......
