Most Popular Hitch Adapters for 2021 GMC Sierra 3500

Hitch arrived on time. Packaging was a little beat up but everything inside was fine. I did the installation myself and had no issues. The install video etrailer made was a big help and good reference. I'd absolutely recommend getting this hitch if you have a gooseneck hitch and are looking for a 5th wheel hitch that can be used with it.

i've hauled gooseneck horse trailers for years with the b&w turnover ball. when i purchased my first fifth wheeler I was in the market for a 5th wheeler hitch. this companion seemed to be a no brainer. happy to report design, function and ease of use exceeded my expectations. excellent product and customer experience.

Fit like a glove. Dropped right in and I installed the 5th wheel hitch in no time. Heavy and well built.

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

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.

only shipped half of hitch said they would over night rest never got it had to purchase different brand else where as we were leaving on trip

It looks and feels great. Nice to be able to use my truck pulling a fifth wheel.

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.

This product is spot on, I installed it immediately and have used it twice. This product was an awesome option to purchase because of already having the B&W turnover ball system. This gave me the ability to install and the Curt Q24 slider to give the maneuverability needed when pulling a fifth wheel with a short box that the Anderson hitch did not provide. I have already used the slider option twice, it works flawlessly. Prior to the purchase of this Demco I purchased the Curt X5. The X5 did not work with my truck at all. The X5 did not even make contact with the bed of the truck for support. This Demco base to rails fits tightly to the bed of the truck. I have 2007 Dodge 3500. It is a short box mega cab.

Does exactly what is is built to do. I pull a 42’ fifthwheel that weighs 18000# with no hesitation anywhere. As always very happy with product and ther staff at etrailer. I will continue to use you for all my needs. Thank

Simple to use, great value!

Hard to hook up you have to be right over the hitch hole with the trailer pin or it wont drop in

It is exactly what I ordered but I am surprised how poorly the pin clip is designed. I am going to have to replace it with a pin that has a hole for a clip because any vibration will allow this pin it came with to unclip.

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.
