Best 1999 GMC Sierra Gooseneck And Fifth Wheel Adapters

I pull a 14' goose neck dump trailer and a 10,500 lb fifth wheel camper with a 2008 GMC Sierra 1500. Both are obviously all the truck should handle anyways but I would never try it with a different hitch. There's no play, none, in either even after nine years with the gooseneck receiver and one year with the fifth wheel companion. I travel for work and have pulled the camper 6.5 hours. 10,500 lbs on a bw hitch in your bed is more safe than 5000lb on s tail receiver no doubt. Worth every penny.

easy to assemble. great instructions good product

Easy to install and does the job.

Great product! Ive pulled a 42' to Hell and back not one problem. It is heavy, but it's very solid. My fifth wheel hitch fit straight in. Way cheaper than having to put rails in if you have a factory ball hitch in the bed. Its It's also nice that it's removable so you can haul furniture, or things that can't sit crooked ect. Great product, should last forever. Definitely would recommend

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 just received my Demco Gooseneck-to-5th Wheel Trailer Hitch Adapter today. Installed it, hooked up to my first 5th wheel camper I just purchased, and pulled it home from about an hour away. Installation, hook up, and pulling was very easy and I am very pleased with the hitch. My rig is a 2007 GMC 2500 HD pulling a 2007 Sunnybrook Bristol Bay 3150 RL.

I installed the Demco Recon Gooseneck to 5th Wheel Hitch yesterday. The Hitch was installed on a Reese Remove A Ball Hitch and fit perfectly after cutting the rubber mat in the bed of my 2012 GMC Sierra 3500hd Duramax Diesel Dually. I will be hauling a Keystone Avalanche 5th Wheel.

I installed this yesterday on my flatbed with recessed ball and moved our 41’ sierra 20 miles to our shop for service and the hitch works perfect! I couldn’t be more satisfied in this 21k hitch and only took 30 minutes from the time I opened the box until it was installed and ready to go! This hitch is a must for recessed ball flatbed trucks

Great product. Very well constructed and easily exchanges with my goose neck ball reciever.

Easy to install and does the job.

This product fits my fifth wheel hitch well and fits in the truck hitch as well. Have not pulled with it yet as winter storms are here. I expect it to work well. Expensive for as simple as it is. Hoping it is built well. Nice That I was able to get a used one at a reduced rate. Missing the pads so we’ll see what kind of a difference that makes. Very happy with etrailer as a distributor. They make the purchase easy and quick free delivery. They Always follow up on my satisfaction with my purchase’s.

This thing works. No hassles with hitching and I don't have to swap out my fifth wheel from the truck (which pulls the camper too) to use the equipment trailer. The fifth wheel is easier to hitch and disconnect than the ball hitch that it replaced. I see no disadvantages, except that my neighbors can't just borrow my trailer.

Great product. Very well constructed and easily exchanges with my goose neck ball reciever.

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.

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!!

Heavy and doesn't fit flat on my truck bed, had to add some heavy duro rubber shims between this and the bed floor. I paired this with the C611-624 gooseneck 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

Order arrived on time. Packaging looked almost perfect with one corner of the box slightly damaged. Two of us installed the hitch without too much of a problem. It is heavy. Used some WD40 on the inside of the mount. Balance it on the tailgate of the truck. One strong man plus an old guy was able to get it installed. I will update this once we have a couple thousand miles on it.

I had borrowed an adapter from someone. It was the same as the one I purchased from you. I made several trips pulling a four horse goose neck trailer with no problems, so I decided to purchase an adapter of my own.

Fantastic service and follow up

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!
