I bought a new trailer earlier this year, and need to put a winch on it. It's not something I plan to use with any amount of regularity, but more of an insurance policy if/when my car cannot be driven on the trailer. I don't really care to put a battery on the trailer, so I was exploring different quick disconnect options when I came across the old school hand crank winches. Other than a lack of convenience when I actually have to use it, is there any reason I shouldn't go with a hand winch?
