I've got a HF 3k unit. It came with enough line that I can double it up and use a snatch block if I have a vehicle nosed up to my ramps. I don't ever haul anything larger than that, so it has served my needs fine for loading the trailer. I don't leave it on the trailer full time. Its got a quick release plate between the winch and the trailer so I can remove it and store it inside. Had it for about 10 years now.
