Mike, if you are thinking of a gooseneck hitch for your fifth wheel travel trailer......Think Again!
You DO NOT want a gooseneck for a fifth wheel travel trailer. There are quite a number of reasons not to use a goose neck for anything but a stock trailer. You stand a good chance of cracking the mounting on the trailer. They put way too much stress in a very small area. A semi goes by you on the highway and the trailer will rock like crazy. It's a very unstable setup. The reason they work good for a stock or horse trailer is because the trailer is very low to the ground and the center of gravity is much lower. Get a good Reese fifth wheel hitch. You'll never regret it.
