Once I forgot to chock when getting home after a lloonngg trip. When I went to unhook the trailer it rolled back off the leveling blocks and back about a foot...at the same time my wife was taking another load back into the house...it almost hit her.
The first thing out the door is to now put the chocks in front of and behind each wheel on the side the leveling blocks don't go on.
