Driveway Ramps

All my trailers have winches to pull a car in. They have remote controls so you sit in the car while pulling it in. It don't take much to roll a car that rolls free. Like a previous poster had mentioned. Drill a hole through the concrete floor and drive a long piece of steel down to floor level with a hole in the top for a clevis. You don't have to mount the winch just secure it for a pull. Clevis should be at floor level so you don't need a heavy piece of steel.
