after I tried numerous options I finally got this base to sit in the proper place.I had to position the hitch backwards. the rear with the B&W emblem is in the front contrary to the instructions. every position I tried left the hitch behind the rear axle, and positioned my rv hitch almost touching my endgate. other than the installation snafu it is a very sturdy and well constructed hitch.

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.

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.

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!

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.

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!

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 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.

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.

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?

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.

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.

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

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.

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.

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!

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.

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.

- Replacement Hardware For B&W Companion HitchFor 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.
view full answer... - 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.
view full answer... - Availability Of Rubber Foot Pads For B&W 5th Wheel HitchHello Jim, thanks for reaching out. So the replacement rubber pads are not available from B&W as a purchasable replacement part. We have had people ask us about these before and if you reach out directly to B&W they should be able to help you get some.
view full answer... - Is There A Way To Install A 5th Wheel For A Prep Package Onto Above Bed Rails?Hey Sean, We do not have a bracket kit to install a hitch base meant for a puck system onto normal 5th wheel rails. What you would need to do to use that B & W is get a replacement base that is designed for 5th wheel industry standard rails. Ford your truck specifically we do have a base that would work with the B & W head you have now, # BWRVB3500. That would install right onto your rails. What kind of trailer are you looking to tow.
view full answer... - Looking For Replacement Plastic Foot Pads For B&W Companion 5th Wheel HitchHello Michael. It sounds like you are looking to replace the Plastic Foot Pads on your B&W Companion 5th Wheel Hitch. I am sorry to say that the foot pads are not available to purchase individually. We have got this question before and even spoke with the folks at B&W about this. If you contact B&W directly, they may be able to send you some.
view full answer... - Can a B&W Companion 5th Wheel Hitch from a Chevy Silverado Fit a 2018 Ram 3500 Long BedThe 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...
view full answer... - Is There B and W Companion Hitch that Fits Flatbed Hey Ray, since flat beds sit up higher that creates two issues for fifth wheel hitches to attach to gooseneck balls. The shank that would fit into the gooseneck hitch opening would need to be taller and also the base needs to be shorter to compensate for the increased height of the bed. So the correct base you would need is the part # BWRVB3055 but you also would need to for sure have a B and W gooseneck hitch in your truck and not a standard flat bed gooseneck hitch that would have came...
view full answer... - Dimensions of the Base of the B&W Companion 5th Wheel HitchHey 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. The base will measure 18" from the center of the square post, where it connects to the gooseneck, to the edge of the hitch on the cab side.
view full answer... - What Rail Kit Does B and W Companion Hitch for Ram Rail Kit FitThe Companion hitch part # BWRVK3670 that is in the question you mentioned only fits the OEM rail kit that Ram/Dodge would have put in the truck. If the truck ends up having a different brand gooseneck hitch you'd have to go a different route but that would depend on what brand hitch it is.
view full answer... - Is There Way to Use B and W Companion Hitch In OEM Rail Kit of 2019 Chevy Silverado 3500 Hey Dennis, there isn't a way to use your current Companion hitch with the OEM pucks of your 2019 Chevy Silverado 3500. Only solution will be to go with the Companion hitch that is designed to fit your truck with the part # BWRVK3700.
view full answer... - How to Adapt B&W Companion From 2021 Ford With OEM Prep to 2006 Dodge Ram PickupHey Lori! This may be possible but I'm going to need more information on the 2006 Dodge Ram. Is this a 1500, 2500, or 3500? Can you also tell me the bed length and if it is a Mega Cab or not? Depending on the configuration you may be able to install a B&W Turnoverball in your sons truck. This will allow you to swap out the base of your Current Companion with # BWRVB3500 (fixed, long bed) or # BWRVB3405 (slider, short bed) which will be able to install in the gooseneck hitch. If you click...
view full answer... - How Can I Get Replacement Plastic Foot Pars For A B&W Companion 5th Wheel Hitch?Hello Dillon. We have actually talked to B&W in the past about the plastic foot pads and unfortunately they are not available to purchase individually. They may be able to send you some though, so what I would do is reach out to B&W directly. They are usually really easy to work with and they should be able to help you out.
view full answer... - Will The B&W Companion Base Work With Any Gooseneck Hitch System?Hey Michael, The replacement base for B&W Companion 5th wheel hitches, # BWRVB3500, is not universal. It is only designed to work with the B7W Turnoverball Gooseneck system due to the way it latches into the gooseneck hitch. Something like a Curt or Reese would not work. If you have a factory system and its a square hole there is a chance it is a B&W system already. Do you know what style or brand gooseneck your vehicle has?
view full answer... - Availability of Replacement Foot Pads for B&W CompanionHi Allen; the foot pads are not something we have available for the B&W Companion # BWRVB3500. You will have to reach out to B&W directly to see if they can send you a replacement. This is pretty typical for less common replacement parts from B&W, they prefer to send them to customers directly.
view full answer... - Hitch Weight of the B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch AdapterHey Steve, the B&W Companion # BWRVK3500 weighs 205 lbs. The head itself # BWRVC3006 weighs 69 lbs and the base # BWRVB3500 weighs 136 lbs.
view full answer... - Slider Base For B&W Companion Hitch In A 2013 Ram 2500 With B&W TurnoverballHey Bruce, I can definitely help with that. The correct slider base is the Replacement Slider Base for B&W Companion Slider # BWRVB3405. This will install directly into the ball receptacle for the B&W Turnoverball Gooseneck Hitch in your 2013 Ram 2500, just like your RVB5300. The head unit for the Companion hitch is interchangeable so you will not need a new one.
view full answer... - Could B and W Base be Swapped so that it Can Fit Ford OEM Rail KitHey Mark, yes you could replace the current base you have now of # BWRVB3500 with the part # BWRVB3305 and you'd have a hitch designed for the OEM pucks of your Ford truck. How did you like the current Companion hitch you have?
view full answer... - How Much Does the Head and Base Weigh for the B&W Companion 5th Wheel HitchHey Paula, so this a pretty beefy hitch. The base, # BWRVB3500 weighs 67 lbs, and the head, # BWRVC3006 weighs 69 lbs, for a grand total of 198 lbs with all the nuts a bolts. Are you planning on moving this hitch around by yourself? If so, I'd suggest not, and having a friend help you! Let me know if there is anything else I can help you with!
view full answer... - Troubleshooting Installation of B&W Companion 5th Wheel Hitch in 2001 GMC 2500The Replacement Base for B&W Companion 5th Wheel Trailer Hitch - 20,000 lbs # BWRVB3500 will fit any turnoverball gooseneck hitch. The new head # BWRVC3006 basically gives you the B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3500 and if you look at the attached installation details you will see there are a couple different socket post positions and also a socket adjuster to assist.

- Replacement Base for Older B&W Companion 5th Wheel Hitch That Used U-BoltsThe model of B&W Companion 5th wheel hitch you have is the older one that used U-bolts. And while I'm sure it has aged gracefully for the most part, if you have U-bolts that need replacement the only option is to convert your hitch to the new style with the Replacement Base for B&W Companion 5th Wheel Trailer Hitch # BWRVB3500. The reason for that is the U-bolts you are looking for are no longer available. While that is undoubtedly not the news you wanted to hear, a new base is going...
view full answer... - Are B and W Companion and Patriot Heads InterchangeableFunctionally they are the same as they have the same jaw design, but they do attach differently so they are not interchangeable. The Patriot head replacement is the part # BWRVC3200 and the Companion head replacement is # BWRVC3006.
view full answer... - How to Convert Older B and W Companion 3000 to Newer Style CompanionI spoke with my contact at B and W and he told me that you will need to replace the base of your Companion 3000 with the base part # BWRVB3500. Basically you will be able to reuse the head of your current hitch by replacing the base.
view full answer... - How To Convert Older Style B and W Companion to Modern CompanionThe best option to modernize your older B and W Companion is to switch out the base to part # BWRVB3500 so you will not have to deal with finding the correct u-bolts in the future if you need them because they are no longer available. You would just use your current head on the new base.
view full answer... - How to Upgrade B&W Companion 3000 5th Wheel Hitch to B&W Companion 3500You are absolutely right with how you can upgrade your older B&W Companion 3000 model to the newer B&W Companion 5th-Wheel Trailer Hitch # BWRVK3500. Since the head unit is the same on both hitches you can make the upgrade to the newest model simply by purchasing the Replacement Base for B&W Companion 5th Wheel Trailer Hitch # BWRVB3500.
