I'm looking at a trailer package that includes a gooseneck. It is 16' with ramps and two axles. The condition is good. I don't have a gooseneck hitch so I plan to sell it. What is a good asking price? I'm not all that familiar with goosenecks but there sure seems to be more steel used than bumper pulls so I'd assume they are worth around $600-800 more than a comparable bumper pulll? Opinions please.
