Video Transcript for B and W Fifth Wheel BWRVB3700 Review

Today we're going to take a look at the replacement base for the BMW companion OEM fifth wheel trailer hitch for Chevy GMC trucks. Now this replacement base will fit the BMW companion OEM fifth wheel trailer hitch, part number BWRVK3700 that we do sell separately on our website. This base does come with the adjustable pivot arms here that I've installed just to show you where they go. This will let you mount your hitch head, which is sold separately, to fit your application. These pivot arms can install in 2 different horizontal positions for improved cab clearance. When you install them, that also gives you an option to raise or lower the hitch head with 3 different vertical height settings.

That's critical on the height settings because you do want to, when you tow your fifth wheel, you do want to make sure it's level with your tow vehicle. If you notice on the top, it has the polyurethane bushings on these pivot arms. This is where the hitch head will sit onto, gives you a nice quiet, rattle free ride. Now the space is is a very quick, simple installation. Basically it drops into the 4 receiver pucks that are built into your factory underbed rails, on your Chevy or GMC truck. It is a quad return quick lock puck system that will allow easy mounting and removal of the hitch.

Basically when you go to install this into your vehicle, all you have to do is pull the penning clip, rotate the handle, a quarter of a turn - you'll do that on each corner - and that rotates the tab, allows you to drop it into those pucks that are in the underbed system. Once they drop into place, rotate it back a quarter of a turn, which rotates the tabs to lock it into position. Put the pin through the base and the handle, and it will lock it. You do that at each corner. Very simple installation. Now because of that design, it is a rail free design, which means there are no rails in the bed of the truck.

When you do remove this hitch from your truck bed it will allow full access of your truck bed. The finish on this, it's a grey, powder coated steel, which is corrosion resistant. This part is made in the USA. Again, the application on this is 2015 and newer Chevy GMC trucks that have the factory installed towing package. Gross towing weight capacity is 20,000 pounds.

Tongue weight capacity is 5,000 pounds. The vertical height settings, we mentioned 3 different settings, would be at either 16 3/4", 17 2/4 " and 18 3/4". That measurement is once the hitch head is on here. The measurement would be from the truck bed to the top of the hitch head. That should do it for the review on the replacement base for the BMW companion OEM fifth wheel trailer hitch for Chevy and GMC trucks.

There are not words to express how pleased I am with this unit. Right out of the box, 10 minutes to put on support arms, move to position in truck bed and it’s locked down. Ready to set the latch system on and go camping. Great engineering and precision construction. Could not be more pleased. I have been pulling with B&W turn over and Companion hitches for 15+ years. My hitch has been in 4 trucks now. DO NOT CHANGE B&W! Pictures to follow soon. Raining now. Want to show product in sunlight. 611290

Love it. Bought a new pickup, but didn't want to have to buy a whole B&W Companion setup. The new pickup has the puck system from the factory. Was able to get just a new base from e-trailer and works perfectly with old fifth wheel hitch top, great company to work with. 595657

This is a great product, I bought it for my 2018 GMC 2500HD with the factory puck system. It is very simple to put together and is easy to use. I use it to pull my 40' 5th wheel camper and it works well, very rigid unit once it's locked into the pucks which provides a nice smooth towing experience without any jerking. I kept my 5th wheel hitch off of my original Companion setup and it hooked right up without any issues, I highly recommend this hitch. 593545

I had to replace my truck. I then needed to replace my older 3000 series American made BW 5th wheel hitch. After talking with BW I learned I could just buy the RVB3700 base I needed and reuse my older 3000 series coupler. Armed with the BW part number I headed over to my favorite and first choice online vendor, etrailer.com. As I had expected etrailer.com had the part I needed. The part was easy to find, easy to order, promptly shipped and well packaged. I unboxed the hitch and followed the enclosed clearly explained RVB3700 base assembly instructions. The Silverado/Sierra BW RVB3700 puck model was a perfect fit for my truck. My older 3000 series BW Companion 5th wheel coupler fit the new BW RVB3700 base like a glove. I look forward to many more years and miles of towing my 5th wheel trailer. 578208

  • Recommended Sliding 5th Wheel Hitch For 2018 Chevrolet Silverado 2500 with 6-1/2 Foot Bed
  • I spoke with my contact at B&W regarding the Replacement Base for B&W Companion OEM 5th Wheel Trailer Hitch # BWRVB3700 referenced in your question. She stated that you can absolutely use this base to replace the legs on your existing Companion for it to be compatible with the Silverado rail kit. She did also confirm that this will fit the factory rail kit on your 2018 Chevy Silverado 2500. With that being said, since you do have a short bed, I recommend using a sliding hitch that will...

  • Can the B&W Companion # BWRVK3500 be Converted for Use on 2017 Silverado 3500 with Puck Package
  • We do have the Slider Base # BWRVB3770 if your 2017 Chevrolet Silverado 3500 is a 6-1/2 foot bed or the Base # BWRVB3700 if you have an 8 foot bed. These are compatible with the factory prep package in your Silverado and will allow you to use the Companion hitch head from the B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3500 that you already have. Instead of just replacing the base I recommend selling your entire Companion and using that money to offset the price...

  • Solution for Using Old B&W Companion Hitch with Factory Puck System on 2018 Chevy Silverado
  • If your 2018 Chevy Silverado 3500 features the factory gooseneck/5th wheel rail kit puck system, I may have a much easier solution that will still allow you to use your existing B&W Companion. Instead of removing the factory system and installing a completely new gooseneck hitch, I recommend simply replacing the base on your current Companion. To do this, you will just need the Replacement Base # BWRVB3700, which is confirmed to fit the factory pucks (the 4 pucks that are located around...

  • Compatibility of Using an Older B&W Hitch Head on a Replacement B&W 5th Wheel Hitch Base
  • Yes, you will be able to use your current B&W Companion head with the Replacement Base for B&W Companion OEM 5th Wheel Trailer Hitch for Chevy/GMC, # BWRVB3700. I confirmed with my contact at B&W that the Companion heads are interchangeable between the bases. Using the # BWRVB3700 base on your 2017 Chevrolet Silverado 3500 will give you a gross towing weight of 20,000 lbs.

  • Can B&W Patriot Fifth Wheel Head Be Used On Companion Legs For 2016 Silverado With Puck System
  • I called my contact at B&W and asked about your Patriot fifth wheel hitch head. They told me the Patriot head will not work with the companion legs that fit the puck system on your 2016 Silverado. If you decide you want to change out your fifth wheel hitch, we do offer the Companion, part # BWRVK3700 that will work with your pucks. We also carry the Curt Q25 5th Wheel Trailer Hitch, part # C16069, that is also designed to work with the puck system in your truck.

  • Can Companion Fifth Wheel Hitch Work With Factory Gooseneck Hitch On 2017 GMC Sierra Truck
  • If you are asking about a 2017 GMC truck with a factory gooseneck, the Companion will not work for you. The factory gooseneck on GM trucks is made by Curt. If the 2017 GMC truck has the factory 4-puck system in the bed then you can buy a replacement base that will allow you to install a companion fifth wheel hitch head on the base and use it in the pucks. For the replacement base you would need part # BWRVB3700.

  • Can the Hitch Head of a B&W Companion Hitch Fit on the B&W Replacement Base # BWRVB3700
  • Yes, you will be able to take the head off of your current B&W Companion 5th Wheel Hitch and use the B&W Replacement Base for the OEM 5th Wheel Trailer Hitch for Chevy/GMC, # BWRVB3700. The B&W base will fit in the factory rail kit of your 2018 Chevrolet Silverado 2500 truck. The base has a gross towing weight rating of 20,000 lbs and an adjustable height setting between 16-3/4 to 18-3/4 inches.

  • Yes, the B&W Companion 18K 5th Wheel Hitch Head will fit the Replacement Slider Base for B&W OEM 5th Wheel Hitch part # BWRVB3770 on your 2019 Chevrolet Silverado 3500.

  • Can I Use the B&W Companion Hitch From My 1999 Ford F-350 in My 2016 Chevrolet Silverado 2500
  • You can use your existing B&W Companion Fifth Wheel Hitch # BWRVK3500 out of your 1999 Ford F-350 on your 2016 Chevrolet Silverado 2500 if you install the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1016 . However, if you have the factory rail kit in your 2016 Chevy you will not be able to install the gooseneck hitch.

  • Yes, you can take the head of your current B and W Companion hitch and install it on the leg kit part # BWRVB3700 and you'd then basically have the part # BWRVK3700 which is the correct hitch for the rail kit of your 2017 Chevy Silverado.

  • Will B&W Companion # BWRVK3400-5W Fit the Factory Rail Kit on a 2018 Chevy Silverado 2500
  • The B&W Companion # BWRVK3400-5W that you already have is only compatible with a B&W Gooseneck hitch like part # BWGNRK1016 for your 2018 Chevrolet Silverado 2500. Since you already have the factory rail kit already installed on your Silverado the B&W Companion you will need is part # BWRVK3770 for a 6-1/2 foot bed, or part # BWRVK3700 for an 8 foot bed. Even though the head unit, part # BWRVC3006, is the same for your current Companion and either of these options, it would be easier...

  • Recommended 5th Wheel Hitch For 2016 GMC Sierra 2500
  • The factory tow package for most trucks have changed to the puck system for new models like yours. That offers the convenience of not having an aftermarket underbed rail system, but it does make most hitches incompatible. So, there is an adapter, but not an ideal option for your vehicle unless you have a specific pin box on your trailer. For your B&W hitch, you can get a new base with the puck system for a non-sliding hitch, like what you have, but that is not recommended for the 6-1/2...

  • Comparing the Curt Q25 and B&W Companion Hitches for 5th Wheel Towin a Sunnybrook Trailer
  • It is very interesting that you are experiencing chucking and jarring while using the Curt Q25 # C16069 with your 2016 GMC Sierra 3500. This is actually a really nice 5th wheel hitch and has received great reviews from our customers. The only things that I can really think of is that the built-in cushioning may be wearing down or that the jaws aren't completely closing so I would start by checking those out. If you have a cushioned pin box it could be counteracting the cushioning on the...
