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.

Easy installation

Nice being able to buy just a base for my puck system. B&W has a very nice looking and durable product.

Will was a great help shipping got a little messed up but I got in time for our camping trip.



by:

Hitch was delivered in a very timely manner and luckily ok, packaging was in very bad shape, big hole in box and parts everywhere but luckily parts were all there and no paint damage. Your packaging could be improved!



by:

Best hitch that I bought for my fifth w heel



by:

Easy purchase fast shipping



by:

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!



by:

Relatively easy setup. Quick install. Great hooking up the 5th wheel and towing with this hitch.

Easy to install and adjust. Replacement for my existing hitch after getting a new truck.

Wow Lee, thank you very much! And Ill be sure to show Will this review, too. Its always encouraging to have such nice feedback :)



by:

Amber was great to deal with. She doubled checked that the part would fit my truck and was extremely pleasant over the phone. Thank you !!



by:

All installed on my 2025 Sierra 3500 HD. Fits perfect and mates exactly with the old B&M upper. Saved me mony overall!



by:

Easy to install and remove from the truck to use the bed when I’m not towing the camper. By removing the head and base separately makes each lighter and easy to hold onto with comfortable grab holding positions.

Still works great. It easily installs on weekends we use the camper and out easy enough to remove when not in use. The tilt spring is a little sketch and need to tilt it manually then the spring holds good enough for hooking up.
