I’m not familiar with this particular brand of winch, but for that price, I would be dubious about a) how long the motor will last, and b) how well it’ll stand up to being exposed to the elements on a flat bed truck (I stand to be corrected if anyone has one).
Depending how much you’re planning to use it, I would either spend a bit more money on a known brand with good parts back-up, or if it’s only for occasional use, maybe just get a hand winch.
