Great



by:

Packaging was inappropriate. Box arrived shredded with gaping holes and ineffective attempts to repair with packaging tape. Reasonable consideration should be made for shipping a bulky item weighing nearly 150 lbs.



by:

Great service! The new base arrived promptly. As usual, the box was destroyed, but nothing was missing or damaged. Assembly was easy. I will continue to shop etrailer

Phew! Glad that everything arrived with no damage, Mitch. Am I guessing correctly in assuming you got a new base because you got a new truck?

@GwendolynY Yes we got a new truck. The old base was used in a B&W turnover ball hitch that is installed in my 2009 Tundra. That particular installation has a shallower hole, and we had to shorten the mount post.

@Mitch Congrats on the new truck! How are you liking it?


by:

Simply the best. Been towing large fifthwheels for many years and tried different brands. Have used this brand fiftwheel hitch on 3 different trucks. This one has a higher tow capacity than the older version. B&W is the best on the market period and can't go wrong getting it from etrailer.



by:

The B&W 3500 Base unit is extremely well built. Putting it together and installing in existing turn-over ball gooseneck hitch was a snap. Great information on etrailer's site.
After transferring the old 3000 Companion to a newer truck(2013 GMC 3500HD) was never satisfied with performance seemed to be denting truck bed. So glad the 3500 was created and upgrading to 20,000 lb capacity is a big plus. The older hitch head fit perfect as stated in etrailer's information. Everything worked smooth from ordering to shipping(free!) to installation. Thanks so much.



by:

This B&W RVB3500 base unit is a very good, sturdy product. The head unit mounts securely to the base quickly and easily. The workmanship is top notch, and the base is easy to assemble. I like the fact that the base unit can be easily removed/installed in my truck bed, and that when removed it leaves no mounting hardware that could interfere with use of the bed for hauling cargo.

eTrailer.com is a great company to purchase from!



by:

This was an open box/used discounted purchase which was great because I have a head unit without a base and the discounted price was excellent. It arrived in a very much destroyed box but the contents were in usable but scratched condition. That was fine with me considering the discount! Quick Quick Quick shipping (as usual from etrailer). A Great Deal!

Product is working good as expected!



by:

I made an online order with etrailer.com for a B&W Companion Replacement Base on 9/11/19 and received an email with tracking information and an estimated arrival date of 9/17/19. The base arrived 9/13/19 (two days after my order) in perfect condition. I also received an email containing a toll-free number to call if I had any questions or needed any assistance.

I gave etrailer.com a 5 star rating and will not hesitate to use them for any future purchases. They are OUTSTANDING!

The new B&W Companion Replacement Base is GREAT! Much better than the original.



by:

I was using the RVK3000 base with my old truck. Didnt want to spend the $$ for a whole new hitch as it had only 1500 miles on it. Saw another review on this base and that the old head would work with it, so I hesitantly ordered it. Dang, it got here fast with the shipping upgrade. Box was a little tattered thanks to UPS, but then again it weighed a ton, and all the parts were there. Configured my arms and nervously placed the 5th head on it, and perfect!!! 1.5 inches taller as my 2017 F350 needed and no other adjustments to my trailers 5th wheel pin box thank you !! I am a loyal B&W fan, and etrailer is #1 in my book too... All during this christmas rush !!

Love this hitch !!



by:

Love the new base for my 5th wheel. The easy to use pre-load screw makes tightening down the system much quicker and easier. Also like the poly bars fit in the truck bed slots to minimize side movement. My older base was loaned to a friend and he bent the framework by not tightening the bar to the pin. I was glad to see a higher rated replacement with better features available.

Great product and company to work with, first Etrailer is my go to for service parts, second the customer service is great.

I ordered this new base for a customer who had replaced their truck and their old one would not work with the aluminum bin. Ordered it two days later was on my door step, thank you



by:

The new hitch was higher and allowed my fifth wheel to clear the bed cover I installed on my truck. It was as described and arrived very quick.

Thank you for the great service.

B&W make great heavy duty hitches. My truck is ten years old and have used the same head the entire time. Purchased the upgraded base last year before leaving Michigan for Texas. has been in my truck ever since. Have had no problems or issues what so ever. Super product and etrailer had the best price and super service.



by:

The item came in a reasonable time frame for the order. It was exactly what I expected to receive. Assembled easily as the instructions were very good and clear concerning torque specifications. We have used it to pull a 40 foot triple axle toy hauler multiple times since purchasing this item. We already had the pedestal for B&W companion hitch and it fit perfectly. Very pleased with all aspects of this purchase.



by:

I went this route for a 5th wheel set-up because you can remove the base and not have to worry about still having rails in the bed of you truck. This is a well built base.



by:

the gooseneck hitch base is a great product for B&M. just purchasing the base allows you to use the 5th wheel receiver instead of purchasing both units if you already had the standard rail set up. I preferred to stick with the B&M hitch because I was satisfied with the set up I already had. I feel the gooseneck set up has less noise than the bed in rail style.



by:

I upgraded from the 3000 series to this 3500. I loved the ease of use before, the new design is even better. Easy assembly, great design. The only way to go to make your truck multi use (5th wheel and gooseneck). Fast shipping right to my front door (132 lbs shipping weight, I bet my FedEx guy wondered what in the world I was getting). I'll keep etrailer in mind for any other purchases in the future.



by:

Great product which will help raise my 5th wheel camper 1.5 inches higher than my model 3000 base. This will accommodate the extra height of the bed rails on my 2015 Chevrolet truck. Dealing with e trailer was quick and easy. Their service is excellent. The new model 3500 base came in great shape...no shipping damage....even arrived one day ahead of schedule! Excellent experience for me!



by:

The service and communication from the crew at etrailer.com was amazing. I got emailed tracking alerts along the way and they helped ensure that I'd receive my replacement base before my next trip. etrailer.com is turning out to be my new go-to supplier for my trailer needs.



by:

Wonderful sturdy B&W hitch. Easy to remove from the truck when you need to use the bed. Quick secure hook up to trailer with quiet secure towing. Couldn’t be happier!



by:

Great hitch. My trailer across the scales is 18450.
Glad to see that this hitch has been upgraded to handle my 43 foot triple axle cyclone toy hauler.

The product was excellent this is a product review I do not understand how the other reviews post about service . I am still looking for the service review.... But THE PRODUCT was as I would expect a MANUFACTURER to make it... Thank you B&W Hitches



by:

Love the rvb-3500 converion kit that brought my B&W Companion hitch from 18, 000 to 20, 000 towing capacity. Etrailer did great on getting my product to me quickly and at a great price!



by:

B&W BWRVB3500 Companion Base was delivered as promised. Great price, great product, great service from Erika. Will recommend etrailer to all.



by:

This is great. I upgraded my Companion to the newer version for added towing capacity and the extra height helped too. The B&W system is awesome. I pull a 38 ft Toyhauler and this sytem works great. Cathy in customer service took my order on a Monday and I received it on Wednesday in California! She was a treat to work with. I called regarding a component that didn't come with the kit. It wasn't supposed to, but they contacted B & W and they are sending me the part at no charge. Buy your stuff here, you'll be happy you did.

Top notch!

  • Replacement Hardware For B&W Companion Hitch
    For your companion hitch the replacement pivot arms are now only available with the base which for your model 3000 is # BWRVB3500. I'm not sure what u-bolts you are referring to, so I assume it is the chains and that is part # BW1900-2-1600. If you are looking for the saddle pin, that is # BW3025-119A.

  • Difference Between B&W RVK3500 and RVB3500 Parts
    The B&W Companion 5th Wheel Trailer Hitch # BWRVK3500 (RVK3500) is the complete 5th wheel hitch that will mount to an existing B&W Turnoverball Gooseneck Hitch socket in the truck bed. The part # BWRVB3500 (RVB3500) that you also referenced is simply the replacement base for this hitch without the head unit. I have attached a couple of short video demonstrations that you can check out as well.

    Hey Rick! The B&W Companion Fifth Wheel Hitch item # BWRVK3500 base measures 30-1/2" wide x 36" long. This is the complete 5th wheel hitch and head that goes with the Replacement Base item # BWRVB3500 you mentioned.

  • Can a B&W Companion 5th Wheel Hitch from a Chevy Silverado Fit a 2018 Ram 3500 Long Bed
    The part number you provided, which in our system is # BWRVB3500, is just the replacement base for the standard Companion hitch which is # BWRVK3500. If they are selling just the base then you will also need the head which is # BWRVC3006. Your 2018 Ram 3500 would also need to have a B&W gooseneck hitch installed to use the Companion. For your truck it is # BWGNRK1314. If you have the factory installed gooseneck hitch then the Companion hitch and base listed above will not fit. Instead...
