I've had both types of trailers and hitches and both kinds of conversions. When I had one of each type of trailer I put a king pin post in the gooseneck trailer because that was a WAY better choice than doing a gooseneck conversion on a fifth wheel trailer. If I only owned a gooseneck trailer and already had the turnover ball, I wouldn't even consider changing it all to fifth wheel. I cut a block of wood and put a dowel pin straight up in the center and put that in front of the gooseneck ball so I could see the dowel pin in the mirror whenever I hooked up and I could hit the right spot every time. I also do that with my fifth wheel trailer because the hitch is too low to see in the rearview mirror. Craig
