Single point slider base worked perfectly with B&W turnover ball installed in the bed. The arms were easy to adjust height and distance.

Works great. The best slider ever operates very smoothly back and forth. The ride is the best Ive ever had also. Chucking, surging and bouncing all reduced from other hitches. Never owned a airbag style hitch though.

by: James 09/18/2023

Great hitch we bought to tow our new fifth wheel trailer. Would highly recommend it to anyone towing a fifth wheel. I also want to say I loved the customer service I got from Justin at E-Trailer. I originally ordered the wrong hitch for my Dodge Ram truck but he made sure that I reordered the right one and he even arranged for the freight company to come pick up the wrong one at no extra cost to me. That to me was the best customer service help I've ever had. Thank you Justin and thank you E-Trailer. I will totally use this company again.

My hitch is still working fantastic. My wife and I just got back from a two month trip with our trailer and hitch and it worked flawless.

Worked well, once I read ALL the instructions. Hauled it to Alaska to place on our truck up there. Nice working with the company. Very satisfied with service, delivery, and the product itself.

This is a well built product! I would buy a B&W Hitch again! It is a little on the heavy side but I would rather have that since you are pulling a lot of weight and you need a substantial hitch. I have an electric hoist setup to remove it from my truck. I know some will say go to the Anderson hitch but I've already spoken with two people that I have run into on camping trips that have had their Anderson hitches fail.

by: Donald 06/15/2023

The B&W Companion slide base works very well and eliminates all concern with 5th wheel travel trailer contacting truck cab/back window when negotiating a tight turn into fuel stations, RV camp grounds, and narrow driveways. I strongly recommend anyone who has a vehicle with a 6’-6” truck bed purchase a complete B&W Companion Slide Base hitch or be prepared to dish out money for truck and camper repairs!

by: Leland H 06/26/2017

Purchased my second hitch from etrailer along with several other items and I had a small issue with one electrical plug that was taken care of immediately by etrailer. All of the staff I talked with especially Cathy T was more than helpful this is about the 6th item I have purchased and they are the first ones I turn to for solutions and serivce and prices A+ all the way

by: Erik L. 06/03/2019 One Year Later

B&W makes a great hitch, however if you are in need of slider I think there are better options. The slide mechanism would bind and not slide. The unit is HEAVY.

Just as described excellent product I will buy from etrailer again

The base for my hitch shipped quickly by freight. The delivery was able to drop it in the bed of my truck so I wouldn’t have to lift it in. Install was easy and I was able to pull my 5th wheel that day. Great product and great company.

Happy about this purchase it fit perfect in the bed of my truck. Was delivered exactly the date I was given, I definantly would use etrailer again.

by: CharlieC 06/08/2018 One Year Later

Best choice for short bed trucks. You can make tight turns without hitting your cab with the trailer and doing $1,000s in damage.

by: Jeff 05/11/2023

Really made well however on a 23 gmc the tailgate must be down to have it in the back position.

I order a slider base for my B&W 5th wheel hitch. I had a long bed pickup with the Ford puck system but my new F350 has the B&W turnover ball Installed. Slider base is as solid as can be, has a clean and beautiful finish that will last a decade or more. Slider hitch mover easily and is just watching I needed.

by: Neill 05/05/2023 One Year Later

Works fine. Easy to install and operate. Eliminates most,but not all, pin movements. No problems.

Can B and W Companion Hitch be Converted to a Slider Hitch
Hey Gary, yes the base of your current B and W Companion hitch part # BWRVK3500 can be replaced with the # BWRVB3405 which will then convert it to a slider hitch. Did you get a new trailer with a wider nose and need more clearance or did you switch to a short bed truck?

Parts Needed to Convert B&W Companion to 2019 GMC Sierra 2500 w/ a Factory Puck System
There isn't an adapter, but there is a way to convert your B&W Companion Sliding 5th Wheel Hitch # BWRVK3400 to work in your 2019 GMC Sierra 2500 short bed with the factory puck system, which is simply to replace the base of the unit. All you need is the Replacement Slider Base for B&W OEM 5th Wheel Hitch - Chevy/GMC Towing Prep Package # BWRVB3770. This will allow you to attach the hitch to the puck system and is the only thing you need. I have added a link to a video review for you...

Recommended 5th Wheel Underbed System for 2015 Chevy Silverado Short Bed with Gooseneck Integrated
There is only one option to help you get the gooseneck and rails you desire in your 2015 Chevy Silverado 2500 short bed. The standard rails attach at the same locations as the gooseneck hitch brackets so individual options are not compatible. My recommendation is to use the Reese Elite Series Under-Bed Gooseneck Complete Hitch # RP30158-68 which will give you the underbed gooseneck hitch and the underbed rails with the pucks for a clean bed when not in use. Then you can use your current...

Is The B&W Companion Slider Base BWRVB3405 Vehicle Specific?
Hi Virgil! The Replacement Slider Base for B&W Companion Slider 5th Wheel Trailer Hitch - 20,000 lbs # BWRVB3405 is not a vehicle specific part, but what it attaches to is. Do you have a B&W Turnoverball underbed gooseneck hitch in your Ram? Or is it the factory gooseneck hitch? If you don't have the Turnoverball and want to go with the Companion hitch, let me know the year and model of your Ram and I can find one for you. The bed size and any other style break out would also help.

How to Adapt B&W Companion From 2021 Ford With OEM Prep to 2006 Dodge Ram Pickup
Hey 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.

Replacement Base Needed For Switching A B&W Companion Over From Ford To A Chevy/GMC
Hey Kevin, Yes, the base of your Companion can be swapped out with the # BWRVB3775 if your 2023 Chevy Silverado 2500 has the in-bed puck system. If you don't then you can swap back to the Turnoverball base # BWRVB3405 and install the Turnoverball hitch # BWGNRK1020-5W in the bed.

How Can I Convert My B&W Base to My New 2024 Ford F-250 with OEM Prep Package?
Hello Thomas, I do have a solution for you, but unfortunately there isn’t a way to convert the Replacement Slider Base for B&W Companion Slider 5th Wheel Trailer Hitch # BWRVB3405 over to your OEM Prep Package. Since you already have the B&W Companion, the only way to use it with your Prep Package is to swap the base. The Replacement Slider Base for B&W OEM 5th Wheel Trailer Hitch for Ford Towing Prep Package 20K # BWRVB3370 would be the correct base, and it will let you keep using your...

Will the Reese Aftermarket Puck System RP39FR Fit a 2023 Ford F-350?
Hey David! Sorry to tell you but there were some major changes made between the 2022 and 2023 model years for the F-350's. The 2023 model year was the first for the 5th generation Ford trucks so the Reese Under-Bed Gooseneck Trailer Hitch item # RP39FR will not fit. It fit the 4th generation Ford F-250s and F-350s from 2017 - 2022. I do have a solution for you though.

Can B&W Companion for GM OEM Prep Fit 2025 Silverado 1500 Without Prep Package
Hey Jim! The B&W Companion is designed to fit the prep package or the Turnoverball. If you want to use it in your 2025 Silverado 1500 you will have to add the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1019. You will also have to trade out the base for the # BWRVK3500 if you need a fixed hitch or # BWRVB3405 if you need a slider. Do you already have base rails installed in your Silverado? If you already have rails and don't want to switch to the Turnoverball the best option...

Slider Base For B&W Companion Hitch In A 2013 Ram 2500 With B&W Turnoverball
Hey 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.

What Is The Difference Between B&W RVB3405 And RVK3405?
Hello Brian. So, the # BWRVB3405 is the part number for the Slider Base for B&W Companion 5th Wheel Hitch. The RVK3405 is the part number for the entire Companion Hitch. So, you would get a complete hitch - base and head unit. Our part number for this is # BWRVK3400. This hitch is designed to work with the B&W Turnoverball Gooseneck Hitch.

Is There a Difference Between RVB3405 and RVK3405
There is no difference between the base # BWRVB3405 and the base of the complete hitch # BWRVK3400 (also known as the RVK3405). Are the strips on the bottom of the hitch lined up with the lowest portion of the bed corrugation?

How to Convert a B&W Companion 5th Wheel Hitch From OEM Puck Style Base to a Turnover Ball Style
It sounds like you have the B&W Companion OEM 5th Wheel Hitch w/ Slider for Chevy/GMC Towing Prep Package # BWRVK3770 in your 2016 Chevrolet Silverado with 6-1/2' bed and prep package. For the other Chevrolet that has the B&W turnover ball set-up, you can use the Replacement Slider Base for B&W Companion Slider 5th Wheel Trailer Hitch # BWRVB3405.

Can The B&W Companion Fit Into A Ford OEM Puck System Gooseneck Hitch
The B&W # BWRVB3405 is not compatible with Ford's OEM puck system, which has a standard round gooseneck hitch. You would need to swap the base to part # BWRVB3370 in order to fit the hitch inside the pucks instead.

Difference Between B&W BWRVK3400-5W and BWRVB3405
The BWRVK3400-5W is the complete B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter and the # BWRVB3405 you referenced is just the slider base that does not include the head assembly. You would purchase the # BWRVB3405 if you already had a B&W Companion like the # BWRVK3500-5W and wanted to convert it to a slider. I included a video for the B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400-5W for you to take a look at.

Can a Sidewinder Pin Box be Locked Out to Work with a B&W Companion Hitch in a 2016 Chevy Silverado
Sidewinders are not compatible with the B&W Turnover ball hitches that attach to a single point (gooseneck ball hole) in the truck bed. The reason is that a Sidewinder gets locked out at the hitch so the trailer turns back at the turret which is attached to the trailer. The force applied to the hitch can cause it to twist the gooseneck hitch which would require replacing the whole gooseneck hitch. A Sidewinder can be locked out to function the same as a regular pin box though. To do that...

This is one of my favorite towing setups because you gain the ability to tow either a 5th wheel or gooseneck trailer, the installation looks really clean, and it's all made here in the USA!
