Received my gooseneck adapter quickly and was everything I hoped for!product comes unpainted which I preferred so I could paint it myself to match my trailer. very easy to install in 10mins now I can pull my gooseneck and fifthwheel camper without changing out hitch thanks etrailer!



by:

Well built, durable. Bought 3 of them, 1 for each trailer! Painted to match my trailers. Hard to find quality products with a competitive price in today's economy. Will buy again if need arises, have regarded highly with others seeking alternative coupling solutions.



by:

Got it in 2 days and it is a perfect fit and hookup to my fifth wheel.



by:

I have been very pleased with the gooseneck to 5th wheel adapter. So much so, that I bought a second one (but it was square tube not round). Having a fifth wheel camper, a flat deck trailer and a dump trailer all on fifth wheel hitches is awesome. They pull better than gooseneck (smoother), they hook up faster and nobody asks to borrow them!



by:

As a welder fabricator myself, the product and fabrication is well done.i like that it was not painted so I can match my trailer color. I don't worry pulling my 21,000 trailer and equipment. Thanks etrailer.



by:

This is a very high quality fifth wheel tube for a gooseneck trailer. Highly recommend this tube!



by:

Makes for a more stable hitch with the Ram Puck System, don't hear of feel the gooseneck down pipe flexing, makes hooking up easier in that I don't have to get up into the bed to close and lock the gooseneck lock. Yeah, glad I went this way. Easy install.

Excellent, I converted all my goosenecks to fifth-wheel kingpin setups. While the fifth-wheel hitch takes up more room in the bed than the gooseneck ball, the fifth-wheel couples and uncouples without having to get up into the bed. Additionally, with this setup, I no longer get the sway when braking or hard accelerating that comes with a gooseneck. This is true on all four of my four formerly gooseneck trailers.



by:

Work great. This sure make hookup and drop a lot easier.



by:

Don’t know if UPS damaged the packaging or they received it that way. Also need to talk to UPS because they just left it in my driveway. Haven’t made it home to check the package to see if the other item is in there and not damaged

That box does look roughed up. If anything is damaged then we can replace it. I will have our Customer Service team reach out to you.



by:

Very well made. Paint to match.

Over 80,000 miles later it is working like new. Quality all the way



by:

It fit exactly like I wanted and it looks great



by:

Excellent service. Very helpful over the phone when I ordered the item I wanted.



by:

Saves a lot of time instead of pulling the 5th wheel hitch in and out of the truck. I will use it on a short haul but if I was to go cross country I would go with the original set up. It does sit on a slight angle on the way it’s designed



by:

First time dealing with this company and I promise to you, it won’t be the last time. Very pleased with their online ordering and payment method. My item was shipped to me within 48 hours.



by:

Wont work need send back makes trailer sit to high in front



by:

All welding looks great. Installed in a couple mins and ready to go. The only negative I see is the need for paint on the product. Everything else is great



by:

Works great, I'm very happy with it!



by:

Works great. Does make the trailer pull different.

I did have to lower my 5th wheel hitch in bed to achieve same pull height.



by:

Exactly as described in the video and product description. Very happy with this purchase.



by:

Really happy with my purchase. Order got processed and shipped out to me the same day. I was surprised to have gotten a tracking number to my order within an hour or two after placing my order. As for the the product itself. I’m very satisfied. Easy install. 10/10 would definitely recommend.



by:
