I pull a 36ft prowler fifth wheel 15K loaded gooseneck set up. My wood hauling trailers are gooseneck 20ft with 4ft high side boards. Trailer weighs 4500lbs empty. I add 5 cords of cedar and I am pulling around 15,500 lbs to Vegas. Gooseneck works great. Don't even know the load is behind me until I start to climb. Really much easier set up that the standard fifth wheel in the bed hitch. Gooseneck takes up less room and is easy to load.
