Why is 5th wheel standard vs Gooseneck?

Been doing a lot of research in my preparation for buying a fifth wheel. One of the things that has surprised me is the use of the 5th wheel over a gooseneck design. Considering the weight and space taken in the bed of the truck, why aren't goosenecks a standard in the first place?

For my own needs, I already have a gooseneck ball in my truck so I'll be doing the Reese Goosebox from the start as it seems to be the best option out there. Just curious if there was a solid explanation on why the industry went one direction versus the other...
  • Reese Goosebox weighs about 225lbs. My Pullrite Superglide weighs nearly 300, but I know other 5th wheel hitches weigh less than 300, so weight difference is probably overall minimal. Of course, if Goosebox REPLACES existing pinbox (which Im guessing it does), then weight differential is greater.

    I believe the Reese Goosebox is the only gooseneck that Lippert will not void the warranty if you use.

    Ease of hookup is another Im sure, but how much harder is it to hook up a gooseneck than it is to hook up a bumper pull TT?

    In terms of why INDUSTRY went this way, Im sure it had to do with the frame stresses and the ability for manufacturers to use cheaper pin boxes, and not have to worry about compatibility. If a buyer wants a different pinbox, they will ask for it and pay for it accordingly.

  • I agree with both of above. Easier hookup since it is self aligning side to side and stops and self latches when the pin is all the way inserted. And no safety chains required.

    And the manufacturers don’t have to build the frame as structurally strong, meaning less expensive. Broken frame welds is not uncommon even with a 5th wheel hitch. That is why some manufacturers say they will void the warranty if you use a gooseneck adapter.
  • It is due to the frame stresses. Look at how heavily built your goose neck trailers are up front. It would cost too much to build an RV that heavy.
  • My guess would be easier hook-up. With a 5th wheel you have about a 10 inch wedge you need to fit a 3 inch pin into. With the goose you need to get the things ligned up almost perfectly to lower it onto the ball.
