Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter - Inner Tube - Round - 25,000 lbs

by: Zach H.08/16/2017

Great product. Very well built. I am a farmer and use it to hook up a goose neck trailer to our semi. We use the trailer to haul hay, machinery, or even cattle. What's great about this product is that you can move it from trailer to trailer. This adapter will fit in a gooseneck trailer with the pin running through the side or with the bolts on the front. Overall great product for the farm. 420980

The holes through the round tube insert for pinned height adjustment are not at a right angle to the square plate. I am not sure if it's designed that way on purpose or not. I would have thought it would have went exactly cross ways and not at an angle? The pictures look like the holes are for the pins to go straight thru from the side. I will not be using this feature at this time but maybe in the future. It's welded great and not warped and appears square in good shape but does have some rust. Primer at min would be helpful. It arrived very quickly about 2 travel days plus the weekend, 1 day ahead of schedule. This should solve the problem of leaning/ rolling trailer on the goose neck ball for high leverage loads by converting to anti sway 5th wheel set up. 458153

This item is ONLY for Bull Dog tubes requiring a 15 degree offset. I did not know this until after putting it in my none Bull Dog tube (I have a Lippert chassis). Tested after installation and the offset was so pronounced that it caught on my receiver. Talked with manufacturer's technical expert, and he said that the industry standard is 15 degrees. Regardless, the adapter is expertly fabricated and of good strong steel. Just wish it worked for my trailer. etrailer.com was very good trying to resolve my concern to point Donna spent a lot of time researching a solution for me. Ultimately I shipped back the adapter because it was not doable for me. We both learned a lot today about trailers and the limitations on Bull Dog adapters. 461653

I bought a fifth wheel camper trailer and mounted a B&W Companion hitch onto the gooseneck hitch in the bed of my truck. It is such a pain to take in and out, so I bought one of these for my horse trailer to see how they work. They work great, so great in fact that I bought two more for my stock trailer and flatbed trailer. The only negative I have is that the holes in the sides of the pipe for bolts, pins, etc., are not located 90 degrees from the front of the hitch plate and therefore will not line up with the holes in most receivers on the trailers. They are apparently drilled before the plate is welded on, because none of the three I bought are in the same relationship to the front of the plate. 369013

I love these adapters. They make it possible to use my truck's 5th wheel hitch for my rv trailer, stock trailer and flat bed trailer (plus, they are much easier to hook up than the gooseneck hitch was). I would recommend these adapters to anyone. Thank you for checking back with me. I am very pleased with the service your company has given me over the years.

Bought this so my wife could load and unload our 30' flatbed easier. The gooseneck required her to climb into the bed and was hard for her to line up. This adapter installed in less than 60 seconds and has made her new career as a hot shot driver that much more enjoyable. I couldn't be more happier. 445862

I have ordered alot from etrailer and always been pleased , last week I ordered a 5th wheel conversion for my gooseneck trailer then went outside and literally cut my gooseneck hitch off , i then got a call from etrailer saying the part I ordered was backordered and was not available .while I was disappointed I was so glad called me immediately and was able to come up with a alternative . Great customer service ,I can not say enough great things about etrailer 492683

This is the third adapter I have purchased from etrailer. One for my horse trailer, one for my dump trailer and now one for my equipment trailer. A little bit of time to paint and install and everything is fine. No more climbing in the pickup bed to hook and unhook, no chains to deal with. I prefer the 5th wheel to the ball gooseneck, much easier hook up when you can't see the ball in the bed of your truck. Quality is very good and they work. You won't find it cheaper anywhere else and they always ship quick. 357080

Still doing what they are supposed to do and holding up very well. No complaints.

Worked like a charm, haul for a living and slides right in every circle gooseneck hitch. Only recommendation for company for buyers is to clear coat it because when not in use it will surface rust with in a couple days. Otherwise affordable quality buy! 344645

The product is heavy duty as expected and the welds are excellent. The pipe/tube fit my gooseneck receiver perfectly. The only disappoint was that the drilled holes for the securing the unit to the neck of my trailer were drilled out of alignment with the neck of my trailer and this caused the base plate to sit off center with the fifth wheel hitch when connected to my truck. Fortunately I'm still able to use the unit, it just looks wacky. 286455

I considered building this myself, but for the price, it's a good deal and does the trick. The only thing I dislike about it is are the 4 triangle shaped gussets at the base. I would have preferred to see a collar used (4 inch ID, 5 inch OD, 1 inch height) to marry the pipe and 5th wheel plate. I believe this would have provided a more positive weld and also permitted a deeper penetration of the inner pipe into the goose neck outer pipe. 94411

I own a small transportation company and needed a way to minimize hookup time for one my drivers that primarily pulls fifth wheels hookups. We bought a 30 ft gooseneck trailer and found we needed a faster solution. We reached out to etrailer and they had solution that worked perfectly. Also, we were able to get our hitch conversion within 3 days limiting our downtime. I will buy from these guys again!!!! Excellent service.... 231711

Worked perfect thought fitment might be an issue but it slid in perfect and gets the job done very satisfied especially considering the price would definitely recommend if switching from a gooseneck to a fifth wheel 283999

Plate was bowed during welding process when plate was attached to tube. The plate and holes of inter tube did not line-up with outer tube so plate is square with trailer, off 10-15 degrees, when pin is installed thru hole. Will be able to use it on the one 5-th wheel hitch but not the other one that needs a special plate for the slider hitch to work, being that the tube is not square w/trailer. 215224

Bought to convert gooseneck flatbed to fifthwheel so I wouldnt have to change my hitch every time. Problem solved. Made of good material with good welding. Fit right into my hitch. Hooks right up to my fifthwheel hitch. It was not de-burred or painted. Braces were too high to access lowest hole. Looked like they finished welding it then loaded it in the box and shipped it. Good for price. 247638

by: JoelW06/07/2016

Very heavy duty hitch. Installation was a breeze. Took maybe 5 minutes. The only complaints that I have is A.) you have to paint it and B.) the square plate was welded onto the tube crooked. No big deal it won't affect the function it just looks odd. Don't get me wrong I would definitely buy this again. Now I don't have to take out my 5th wheel hitch to use my gooseneck trailer. 258858

The product recently received from E-Trailer has been received and installed in a pickup. We live many miles from a dealer and when I called for availability and price, they had nothing like that in stock. They would have to order it in and the shipping charges would have been additional charge. Thank you for your prompt service in handling my order. 131728

by: Dennis04/26/2016

Product was just like described, fits perfectly and was reasonable priced to boot, this will have pulling regular gooseneck trailers much easier since I do not need to remove the 5th from my pick-up that I use for pulling my RV trailer, If I need anything trailer related in the future etrailer.com will be the first place I look. 246935

by: Jim W.03/03/2015

The gooseneck to fifthwheel adapter that I received from etrailer is of top quality, the first one was received about a month ago and was so satisfied with the first one that I just had to get another one for another trailer . The price was very reasonable and free shipping made a real deal closer as well !!! 176773

by: Larry L09/27/2016

This does exactly what it says it does...lets you use your gooseneck trailer with a 5th wheel hitch. I have not converted all my gooseneck trailers with one of these. The only thing I would be able to complain about is that the holes in the side are not square with the flat plate which holds the hitch pin. 300584

by: Keith Barker08/12/2016

Upon receiving the product the plate is welded to the tube is crooked. So when it's mounted it's looks bad. 283135

Product arrived promptly; and was as expected, and in good condition. Packaging was appropriate. Product works! I painted mine. I would definitely order from this company again. They have a lot of stuff for different kinds of trailers, and parts that are hard to find in any store. 429740

by: Robert J04/24/2017

Love the product. Great conversion only 2 issues (can't use lowest hole due to supports being to high up the tube as well as the plate is not sitting square. it's off about 30 degrees when pin is put through hole.) Would buy it again and recommend it just a few things. 371607

The product is still working perfect and the best purchase ever. Thanks

by: Mack04/17/2015

I have yet to install this on trailer, it looks like my scre locations are in a different location from holes. I am looking forward to just having one type of hitch in my truck. maybe just the option as I am running a couple different trucks. 185576

E trailer is great I replaced. My goose neck ball to a fifth wheel plate from etrailer fit perfect and works as it should the trailer is an enclosed car hauler is every stable would recommend it to anyone making the switch! 320924

The king pin post I got from you works great I did have to grind the gusset down A little to get the trailer to set level. I was hooking it to a semi truck. That is higher then A pickup. Thank you. D.A. Kramer 463094

by: Steve S.04/20/2016

Delivery was quick. Looks very sturdy and should handle the job of converting my gooseneck equipment trailer to pull with my 5th wheel hitch. Have not used it yet but have it installed and plan to use this weekend. 246250

I received the receiver on Friday afternoon. I am please with the delivery timing. I have not put the hitch on yet, however, I have inspected and believe it will work for me, Thank you for the quick service. 340950

I bought two of these and both are working well on my trailers.

It is a well built product! I did expect it to have black paint on it like the picture on your Web page showed! I was not told on your website that it would need to be painted! Thank you , George A. Stone 255088

The adapter was just what I needed. It kept me from having to install an additional ball hitch on my truck. It is easy to use and cost much less than my other options. I am very happy with it. 332665

by: Brad M.07/27/2016

Very fast shipping. Appears to be good quality. Wish it were at least primed but then I guess it would add cost. Have not had a chance to install yet but it appears that it will fit perfectly. 276648

by: Lawton L.04/11/2017

My wife and I use a heavy gooseneck flatbed on our farm .We also have a fifth wheel rv. This makes the hitch interchangeable. We regularly load 10 tons on the flatbed and have had no problems . 365860

by: James01/09/2018

Craftsmanship looks good, and it was shipped promptly. *Note* raw finish means you will have to prep it for whatever coating you want to put on it. I painted it to match my trailer. 465944

I like the workmanship, Except for height adjustment hole locations. The degree of the holes makes the kingpin plate Off Square. It will work ok. 399881

by: Ken01/22/2018

Was very well built. Had to do a little fabrication to my trailer to get the height right but metal in stem was plenty thick to weld to 468817
