Did not fit on truck!!!!!! called etrailer said it was the right one and told me to call B&W. B&W said there was a problem with those hitch's fitting on chevy trucks's. this is something etrailer should have known.I should not have to spend a 1/2 day on trying to find a solution! I am not very impressed with etrailer at this time>

Hi Denis. I haven't heard of there being any issues with this fitting GM trucks, so I contacted B&W as well. This is what I got back from them: The # BWRVB3710 will fit the 2026 model year trucks. We have heard of a couple of instances where the 2026 GM puck system was welded incorrectly like they were for the 2025 model year, although that has been extremely rare. So with that being said, how is it not fitting? Could it be an issue with the truck and not the B&W base? They hold themselves to very high tolerance standards and I don't think I have had one of their products have a defect in the over a decade I have been doing this.

by:
B&W is so much better than any other brand of 5th wheel hitch I've ever had! There is NO chucking or any noise from this Companion hith. Will never buy anything but B&W again....
by:
It is a perfect fit for my 2023 3500HD, and very simple installation into the factory puck system. Great setup.

Purchasing a newer truck and this will fit the new system. I was really amazed at how quickly I received this new base (ordered and had it the next day). The customer service was great!!
by:
So much of an improvement from the turnover ball version. This one is a smaller footprint, significantly lighter (though still heavy, but not 120lbs heavy). So far I couldn't be happier with it.
by:
Fast shipping, excellent quality, easy to install!
by:
It fit my truck and I expected it would, but I was able to use my old 5th wheel plate from my 05 Companion and save a few hundred bucks.
by:
Great place to go to for all
Your trailer needs.
by:
First of all I was not very happy to have to spend the money for a new base because of the puck system already installed on my truck but when opening the box and seeing the base I was impressed with how much smaller it is compared to the companion base. Very easy install and it looks great. Would give 5 stars but have not connected to trailer yet.

Arrived on time directions were easy to follow .

Received the hitch replacement base this morning. Just got it installed. Absolutely perfect fit and function. The old saddle fit perfectly on the new base. I recently traded our 2015 Denali HD 2500 for a 2020 Denali HD 3500. A very special shout out to Korren in customer service for helping me get exactly what I needed. BTW; the free shipping was super fast! Thanks etrailer. You have a very satisfied loyal new customer!

It’s a great looking and hitch. The only thing wrong with it is missing the bolts to put it together.

Fast and easy! Fits perfect really nice being able to just order the bottom base due to us getting a new truck. We chose not to go with the slider get a lot more room with just a stationary hitch can almost turn 90 degrees got to about 80. All in all great service and great products. Thank you.
