How to keep winch cable from bunching up on one side

1. You shouldn't be near the cable when winching a heavy load so use an anchored pulley to center the cable or whatever it takes.
2. I would suggest you use the the emergency break away system on your travel trailer in the event the winch cable breaks or some other failure occurs. A runaway travel trailer flying down a driveway gives me the shudders, especially if I lived across the street from you.
