As well as some of the reasons already mentioned favouring 5th wheel hitch I think making a hitching error with a ball hitch is more likely than with a 5th wheel coupler.

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.


Most of the RV's on the market have frames made by Lippert. Lippert endorses the use of the Reese Goose Box with their frames so apparently the frames don't need to be any heavier or cost anymore than they already do.

I'm with Adamis, they should at least make it a factory option so you don't have to toss the factory boat anchor when you make the swap. New Horizons makes the Gen Y available on their units.

Aside from ease of hitching there is a lot to like with a gooseneck over a std. hitch.


Lippert 5th wheel frame failures and these were using standard 5th wheel hitch....Lippert/JUNK ---words are interchangeable!

Lippert approves Reese Goose Box cause THEY own it

Could Post all day long but you should do a little bit of research.


To be fair Lippert builds them to what the rv manufacturer designed. Lippert could build the most stout frame imaginable if the rv manufacturer designed the frame that way.

Why is a gooseneck harder on the trailer frame than a 5er? Is it because the length of the neck down to the ball is longer than a 5er?
We are thinking of going from a TT to a 5er, and just trying to learn.


The lever arm on the GN is longer than on a 5th wheel pinbox. On either one, it takes the same force to move the trailer forward. With the longer lever arm and the same force, you get a higher stress transferred to the frame where the pinbox attaches.

Thanks Ken. That is what I was wondering.

It isn't with a modern gooseneck adaptor like a Reese Goose Box.


it would have to be to maintin the trailer high while mounting in the ball in the floor of the bed. your mising the whole hight of the 5th wheel hitch it has to make up for.

And with todays technology of cameras on the cab its easier to line up the ball. I have an Andersen hitch which uses the ball style hookup and I can align it by myself just using the camera without getting out of the seat.

Not everyone has all the cameras, but I can see my fifthwheel hitch in my rear view mirror, but not the floor of the bed.

I agree, fifth wheel hitches are by nature are easier to hitch. Don't have to over raise the fifth like a gooseneck or be concerned about to far forward or backward, chains etc. Plus my fifth wheel hitch breaks down into easily manageable pieces if I need to quickly take it out.

If I were to do any sort of gooseneck type it would be a Reese Goosebox. Goose neck extensions and the Andersen types have no appeal to me.

The additional torque of a gooseneck adapter would be greatest during acceleration and deceleration. But the air bag, shock absorbers, and rubber bumpers of a Goosebox would soften that impact vs a rigid gooseneck adapter.

I have a trailer Saver now (TS3). If I were to make a change I would consider the Goose Box as it has some real design advantages. The attachment point to the truck is low reducing the hitch angle which reduces the amount of chucking forces relative to bouncing forces created by the trailer. Consider the Goose Box image; the forward high hinge point relative to the ball will allow the hitch to retract some when compressed thus mitigating some chucking forces. Solid engineering was used when designing the box.

Any type of soft joint hitch/pin box has to be easier on the trailer frame than a solid hitch and solid pin box.

Yes But the long shaft of the adapter will always create more leverage on the pin box. I don't think I can consider the Goose box a foolproof advantage for 5th wheel towing unless the pin box attachment to the fiver is also altered and reinforced in someway.
A long pipe on a pipe wrench will always create more force/leverage on that lug nut and allow you to turn the nut vs. a wrench with no extension.
Air cushioning and absorption are secondary factors.
