Most Popular Gooseneck Trailer To Fifth Wheel Hitch for GMC Sierra 3500

I ordered the Bulldog adapter because I believe their quality is good. The construction of the Bulldog hitch adapter was good. However, the 4” tube was not perfectly round, approximately.030 out of round. This shouldn’t have been an issue, but since my trailer is used and had a Temco hitch originally, the tube wouldn’t slip in. I chucked the Bulldog in the lathe and skimmed .030 of the diameter and it went right in. This review is not written to criticize Etrailer or Bulldog. Just be aware if you’re working with a different brand hitch other than what is listed, there is a possibility of fitment issues.

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.

Fit and function is great. Item is as described. I’m completely disappointed in the finish quality. They didn’t even bother to remove any welding soot nor splatter and definitely no paint. Hitch is covered in surface rust. The welds were burned in hot but did not wrap the gussets left holes in ones corner and a large weld droplet. No pride taken in the work. Packaging was poor with multiple holes torn in the oversized box with on piece of packaging paper that was supposed to protect this 40 pound hitch.

The 5th wheel trailer coupler adapter works very well. It's strong, solid, and we'll made. Highly recommend!

Great product, fast shipping, excellent communication, definitely recommend these guys!! We painted the square tube/king pin tube red and installed it. Works great, but there is not much of it to see in the pic. Take my word, well built & very heavy duty!!

I ordered this product and received it 3 days later, I took about 1 hour to remove the gooseneck tube and install this one and get the height set for towing, removed it once again and painted it due to it being bare metal. So far this seems to be a quality product.

The gooseneck to 5th wheel adaptor has worked great and is a quality part. I would recommend it to anyone that is transitioning a trailer.

I am extremely happy with this fifth wheel adapter, works great, was delivered in a timely manner

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!

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.

Best customer service experience parts came in faster than expected and well packaged had placed the wrong order the first time and emailed the customer service to cancel order on a sunday replied right away and got me set up with the correct parts definitely my go to place from now on as a first generation farmer and having to deal with many trailers either to move cattle or equipment this is a place of business i can now trust thank you customer service department

This adapter increased my revenue by 25% as now I can haul gooseneck trailers. Highly recommend for simi's that do power only with long slide fifth wheel. I really give it a 10 star

Very well built. Great quality. Some of the edges were a bit sharp from the manufacturing processes, a quick sand with a flapper disc took care of it. Towed approximately 15-20k with it from California to Alabama. No issues at all.

Very good quality. Welds and fit are excellent. I used this to adapt a 5thwheel. The factory pin box was the wrong style to fit my truck and hitch. This coupler adapter allowed me to use vertical adjustment to let my trailer clear the bed of my truck even when turning. As you can see I cut the coupler down to suit my needs and it seems to have worked very well. My only complaint isn’t even really aimed at the part or etrailer but at usps. etrailer shipped the part the next day and I had it within 3days. The box it came in was shredded!!! Again not really the fault of etrailer or the part but y’all might think about using better shipping containers or using a better shipping company. Also wrapping these bigger heavier parts with sharp corners in shipping Cellophane might help keep the boxes in 1 piece. Thanks!!

Perfect for the job if you’re switching from the regular gooseneck hookup to a semi truck fifth wheel set up. Shipping was accurate & I love my adapter! Very easy to attach & real neat finish to paint it whatever color you would like to.

the Bulldog was the perfect fit for our trailer. thank you for your dedicated service in getting the parts correct and them delivered promptly!
