Looking for recommendations on an electric trailer winch to mount directly to the trailer. It's an 18ft dove tail so the ramp angle isn't too steep. Need something with enough capacity to pull a dmax up, but don't want to go overkill and break the bank either. Since it's rolling weight would a 6k be enough or should it be closer to 8k? I'm sure a harbor freight special would get the job done but i'd rather spend the money for a Warn or similar quality and have it last more than a year or 2.
