Nice ride! I recommend using a power winch like the Superwinch LT2000 Electric Utility Winch, Item # 1120210. This winch has a 50 foot wire rope, has a rated line pull of 2,000-lbs, and a plug-in remote. This winch is a high efficiency low amp draw motor that will need 12v power. Make sure to firmly mount it in a stable location on your trailer. The Superwinch is capable of pulling about 4,300-lbs of rolling load up a 40 degree ramp which will be more than enough for your Harley Triglide.... view full answer...
