Most Popular Adapts Trailer for GMC Sierra

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.

I returned it, because it was going to change the structural integrity of my 5th wheel camper. Did not use the product.

Real fast shipping, and a competitive price. Easy to follow directions and simple installation. This is a great product.

I have a 2019 f250 with the 6.5' bed and didn't want a heavy, bulky fifth wheel hitch taking all the bed space up. I had the fifth wheel package already installed as well, so it didn't make sense to not use that. I about went with the ultimate hitch that Anderson offers but decided against that as I have seen many reviews where the hitch failed. I saved a bunch of cash going with this product and it is awesome. I installed it by myself in my drive way in about 2 hours start to finish. I have zero issues turning so close to a 90*. I have a headache rack on my truck and it gets within an inch or two of hitting that but not my truck. I don't have any issues with the king box hitting the bed either like some people stated. The test ride today went very well. It rode very smooth and I have plenty of bed space for my dogs and gear. I would highly suggest this product if you are on the fence like I was. I will see how this will hold up over the years but I doubt I will have any issues. The shipping effected the sheath covering over the cable, I contacted the company, sent some pictures and they will be sending me a brand new part. I love this company and the products they stand behind!!!

I have been using the Ranch Hitch #3100 Straight Adapter for 3 years. Converting the 5th wheel to goose neck was awesome. Much easier to hook up and a smoother, quieter pull. After purchasing a new trailer I noticed that the trailer was too close to the cab of my short bed truck. I found the Ranch Hitch #3139 with 8" offset adapter. It installs easy and gives me 8 more inches away from my truck cab. Excellent! Turning corners is much more comfortable!

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.

Not As Advertised and Horrible Customer Service at Reese! The pinbox came without installation hardware or directions. The hardware took a month to replace and again came without directions. The pinbox DOES NOT have the air valve as pictured. When I called Reese I was told it was due to a parts shortage and the person I spoke to told (Paul) me the new set-up was a dumb design. I TOTALLY AGEE!! To inflate one person has to literally crawl under the pinbox while hitched to inflate while another watches the bar. Not easy for a 60+ year old fat man! The valve faces OPPOSITE the bar side. Just dumb. When etrailer followed up they were basically told I have to live with it. NO - NOT HAPPY!

My camper is 4 yrs old. I was using a gooseneck offset adapter to hitch fifth wheel to truck B&W gooseneck hitch. I upgraded to the Reese 16k Goosebox with a recommendation from a friend. I am absolutely impressed by how this hitch tows. No more chucking, the airbag and shocks add a much needed level of comfort. My camper is a Starcrart AR-One Maxx 26BHS. I’m towing with a 2005 Ram 3500 4x4 CCSB. I am using the B&W offset hitch ball to create more space between the truck cab and camper bulkhead. Highly recommend this hitch to anyone looking to tow their 5’er with a gooseneck ball hitch.

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

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.

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

THIS IS THE THIRD FIFTH WHEEL HITCH THAT I HAVE HAD SINCE 2016. IT IS HANDS DOWN THE BEST HITCH I HAVE HAD AND SEE NO OTHER REASONS TO MAKE ANY FURTHER HITCH CHANGES IN THE FUTURE. THE REASON I GAVE IT 4 STARS IS BECAUSE OF THE LIST OF IMPROVEMENTS THAT I HAVE LISTED BELOW. I HAVE HAD THE HITCH FOR 1 YEAR AND HAVE PUT APPROXIMATELY 10,000 MILES ON IT. WHAT I LIKE: -IMPROVED THE TOWING EXPERIENCE IN TERMS OF RIDE COMFORT WHEN TOWING -UPON DISCONNECTING FROM THE CAMPER, THE ONLY THING LEFT IN THE BED OF THE TRUCK IS THE GOOSE BALL. -REDUCED CHUCKING. IT ELIMINATES ABOUT 90% WHAT NEEDS TO BE IMPROVED: -THE COUPLER ON THE KING PIN NEEDS TO HAVE A FUNNEL (similar to the Anderson hitch) THIS PROVIDES A MARGIN OF ERROR WHEN RECONNECTING THE TRUCK TO CAMPER. WITH THE CURRENT COUPLER, YOU HAVE TO BE DEAD ON WHEN RECONNECTING. A CHEAP ACCESSORY TO HELP IN THE ALIGNMENT OF KING PIN TO THE GOOSE BALL ARE TELESCOPING TENNIS BALLS. -EASIER ACCESS TO PUTTING AIR IN THE AIR BLADDER. IF I KNOW THAT I NEED TO PUT AIR IN THE BLADDER, I WILL DO IT WHILE THE CAMPER IS DISCONNECTED FROM THE TRUCK. I FOUND IT EASIER TO LET AIR OUT THEN TO PUT AIR IN WHEN THE KING PIN IS CONNECTED TO THE GOOSE BALL THERE ARE SOME GOOD VIDEOS ON THE INTERNET THAT HAVE GOOD TIPS AND TRICKS THAT MAKE USING THE REESE GOOSE NECK EASIER. THIS IS ONE OF THE BETTER ONES.

The goosebox is a gamechanger. Easy hookup, no bulky hitch and smooth ride. This completely changed the towing experience of my 5th wheel.

I was sent the wrong trailer adapter. I ordered square tube was sent round.

The king pin adapter works great and I won't have to switch back-and-forth between gooseneck ball and fifth wheel hitch anymore. I found the best price at the etrailer.com .

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!

This hitch reduced chucking very well, I have a 2004 3500 Dodge Ram 4x4 Conestoga riding truck with very stiff suspension, the torsion action of the hitch definitely helps when crossing bridges and pot holes. The 5th wheel is an older Keystone Copper Canyon that is in great shape. I Have 12K miles with the new hitch.

I love this hitch I put it on my 35’ Astoria fifth wheel it pulls great and the shock absorbers help with a smooth ride.we took a ten day trip from Ga to Maine last September and had no problems with this hitch. I guess the only negative is that it’s not as easy as a regular fifth wheel hitch to hook up by yourself but after a few times you can line it up ok. The best thing is that no big hitch taking up space in my truck bed just a ball

This product is a chucking ENHANCER, not a chucking dampener. Additionally, despite what you have read, my experience with GenY customer service has been terrible. GenY will not support their warranty program, they will try to tell you everything is OK, when the fact is, their product is faulty and does not function to GenY product literature statements “Built-In Suspension Creates Up to 90% Smoother Ride”. I purchased the GenY executive hitch from eTrailer on 3/10/23, etrailer sent the wrong unit and to etrailer’s credit - they quickly took responsibility and replaced with the correct unit on 3/24/23. I installed on my DRV Elite Suites PS3 just in time to attend the SOITC rally at the Outer Banks on 4/13/23. When we left for this 750-mile one-way trip, the GenY load indicator was in the middle of the green zone, I measured the pin load at 5,200 pounds. Bedrail clearance was my reason for buying the GenY, it replaced a Trail Air on my DRV and a Reese 27,000-pound hitch on my 2022 F450. Bottom line, the GenY system provided no improvement in bedrail clearance, but did offer the ability to switch in different gooseneck balls to adjust for bedrail clearance. GenY states that a 1,000-mile break in period is required before the GenY torsion system is fully effective. My experience was that at 750 miles the torsion system on the GenY had sagged to it lowest point with the load indicator in the unit outside of the green, this also resulted in losing nearly two inches of bedrail clearance. It looks like it has a metal-to-metal stop so that the lowest the indicator will go is to the white lines outside of the green. I called GenY from the RV park and was told that the unit would not sag further. I purchased a Curt gooseneck ball which was 2 inches higher than the Ford ball to regain bedrail clearance having to rapid ship it to the RV park. Chucking became downright scary on the 750-trip home. As an example, chucking was induced every time my truck’s ten-speed transmission shifted up. Upon arrival home, I again contacted GenY customer service with a full expectation that GenY would replace the unit. Instead, here is their response: “I spoke with our QC Manager regarding your hitch. He said that you are in the correct unit and being at the top end of the green is normal after the break-in miles. As for the bedrail clearance he said that you would be able to lower the pin box down a set of bolts (with our pin boxes you are only required a minimum of 4 grade eight bolts per side) or use a B&W ball as they are roughly 1 1/2” taller.” This is unacceptable...

Without a doubt the biggest difference maker I have ever used in my 50 plus years pulling trailers. When my wife had to concede that the Gen-Y gooseneck hitch made such a drastic difference.... enough said!

The Gen-Y gooseneck has been excellent! I now have approximately 12k miles on mine and it rides very nicely with very limited chucking and handles rough roads very well. I’d highly recommend that you contact Gen-Y BEFORE ordering to ensure you get the correct load rating product. Gen-Y and Etrailer have provided excellent customer and tech support! This product definitely frees up your truck bed and does require a precise line up to hitch.

Makes life a lot easier l don’t have to remove my hitch from the bed of my truck to use it. Just flip the ball and there you go. The gooseneck hitch actually pulls better than the 5th wheel hitch I had. It is rather heavy so come up with a good plan for installing, I used the front end loader on my tractor which allowed me to do the install by myself. Great product!!!

Would bot fit onto my big tex trailer!

It is as advertised. Heavy built. Great construction. Welds are burned in properly. I built a bumper pull to 5th wheel conversion for our camper and it worked great. I highly recommend.

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!

Installation was a breeze. I have not towed with it yet, but am sure it will perform as expected.

Hitch is great. Delivery went well. My only issue is I was able to find it for roughly $xxx cheaper on [online]. When I reached out to customer support to let them know, they told me it was too late to cancel the order and if I’d like, I can return it for a $xxxx shipping fee…

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!!

Man,this thing is GREAT! It was 1 day late on delivery, but other than that, it bolted right up using the existing holes, NO DRILLING! I was THRILLED! It works as advertised, the powder coat paint is awesome, the auto latch works flawlessly. I am very pleased I would recommend anyone wanting to switch a 5th wheel kingpin to a gooseneck to use Gen-Y. They got their act together!

product delivered quickly and packaging was in tack. installation was pretty easy using a tractor. the ride was much improved over a sliding standard pin box system. this system opens up the rear bed space and and allows the ball to be removed like nothing was ever installed. I used the 4 inch offset from B&W to help turning radius on our short bed Ram also devivered from e- trailer. great customer service
