As always, excellent service and support. I called Donna at etrailer to verify dimensions of this replacement 5th wheel adapter pin. Her answers were 'on target' and I was able to comfortably place the order through her. What I wasn't expecting was receiving the component 21 hours after the order was placed! Admittedly, this was a example of timing hitting all the right marks but anything I have ever ordered (lots) from etrailer arrives within two to three days.....usually exceeding my expectations. etrailer will continue to be my 'go to' first stop for my trailering needs. Great website, great service, fair pricing, fast delivery......perfect! 633303

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

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

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 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


Comments
Ended up paying a welding shop to cut and welding it in place because it hung down too much on the lowest setting putting stress on rear axle. Fixed the receiver plate 15 degree offset by cutting the plate off the tube removing the 15 degrees. Glad the Bull Dog was a raw product which allowed modification. Spent an extra $150 in mods to get what I needed.

Works great. Now I don’t have to use the tractor to pull the heavy B&W hitch with the pog system everytime I need to pull the gooseneck. I did have to drill the holes for the pin since the coupler was not a bulldog brand. Pulls better on the king pin than the gooseneck ball also. Great price. Will shop again soon. 646610

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

My expectation when I unboxed the unit was that it would be a brand new unit. This unit looks like it had been made up and peicemealed from random gooseneck parts. I am reluctant to use this unit because I am questioning the workmanship of the welds. 708317


Comments
I reached out to my contact at Bulldog and sent him the photos of your coupler adapter. Based on the photos, my contact confirmed that this coupler is per their prints for the product. This coupler has a raw finish so that the end user can paint it to match the trailer. Because there is no paint or primer on the coupler, surface rust can occur and would need to be cleaned off before painting.

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 just put it on yesterday and it was a very easy install (about 5 Minutes). I hooked my truck up with no problems. I wanted to use my gooseneck trailer without having to pull my heavy B&W companion fifth wheel out of my truck bed. Mission accomplished. 896237

This is the 2nd one I bought for a 40' gooseneck flatbed to road tractor. The first one was seen by an individual that liked it and needed it so I sold it to him and ordered another. They're well built and serves it's purpose. Friendly people n fast service at etrailer. Will use them again if needed. 873118

The bulldog gooseneck to 5th wheel adapter has saved me time. It make leaving the 5th wheel in my truck a reality. Now my travel trailer and equipment trailers are all 5th wheel connections. Back under to connect, simple. They tow smoothly with less jerking. It is bare metal, so paint to match. 870338

Service was great. Product is well made and fit was perfect. I have used hitch to connect my goose neck trailer to my semi for heavier loads that make my pickup strain. Then in a few minutes I change bad to a 2 5/8” ball for the pickup. Anything else I need will be through e-trailer. 801445

excellent product performs as needed . like it so well we just left it on trailer to only use with tractor.Would like to even look into changing pickup over to fifth wheel so it would be easier to hook up trailers with loads.The only issue I had was a small bead that was on the inside of trailer tube that hindered insertion of hitch.Would definitly do it again. We put it on flat bed gooseneck trailer to use with semi so it would free up pickup 791951
