I have one on my pontoon boat trailer. Its more of a pain than anything, even with it wired into my 7 way plug it seems to always be a bunch of work to setup. It replaced the hand which so if you are in a case where hand winching would have worked you have to plug it all in.The best thing for not being able to power load is, back the trailer in to the correct spot so the boat lines up. Then winch it up as much as you can. Then back the trailer up again and then crank it again.
