I have been looking at 5th wheel double tilt hitches, and like the 16k Valley. The goose neck hitch looks nicer as it frees up the pickup bed when you rotate the hitch ball out of the way and cover the 4 inch diameter opening in your truck bed. The setup looks several hundred dollars more because it requires the goose neck adapter for the trailer hitch. Anyone have experience, opinions, pros or cons? thanks. I will be towing a 3400rl.
