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:

We needed a replacement base since we purchased a new truck. It went together and was installed with no issues. We are very happy with it.



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.



by:

Well built and 100% satisfied with this product.

@James Hey James, I have yet to meet a person that is not happy with their B&W products! Glad we had the right base for you =) Any big trips coming up?


by:

We have not started using yet as we don t have our older travel trailer sold yet and have yet to purchase the fifth wheel we are looking at but did set it in the truck for a trial fit and fits perfectly. Thanks for your alls help



by:

Love the puck system. Easy to use lighter than the old standard companion base.



by:

This is a replacement Assy changing from a 2018 GMC 3500 to a 2024 GMC 3500. The puck mounts are different resulting in buying a new base. I had a B&W companion slider but only used slider twice (one to test it). Decided to go with non slider. Just have to make sure I don’t back up too sharp.



by:

This fifth wheel base came to me from etrailer EARLIER than expected! All the parts were there for the assembly, and it fit great! Thank you!



by:

Their website confirmed it was the right fit before I ordered. It was easy, and delivered in two days!!



by:

Great product, easy to assemble, excellant fit & finish, accurate instructions



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!

All of my B&W products are of the highest quality, and they have backed them 100% if there was any problem.



by:

I love how easy this is to install and remove.



by:

I’m hate that they change the puck system in the truck year 2019 to 2024 but it not as bulky as the other one is but everything works good going to set it up this weekend



by:

AWESOME! Perfect fit. Thanks to Kyle on live chat we got the exact item we needed



by:

Hitch fit perfect, had to adjust pucks, head fit great, and looks good I haven't pulled with it yet. Product was delivered quick and as described



by:

B&W IS THE BEST HITCH. THIS THING CAME QUICK, LIKE 3 DAYS! THANKS E-TRAILER. YOU GUYS ARE THE BEST.



by:
