B&W Turnoverball Gooseneck Trailer Hitch

B&W Turnoverball Gooseneck Hitch

Not only does this kit provide you with a sturdy, custom base for installing your Companion fifth-wheel trailer hitch in the bed of your truck, but it also doubles as one of the most recognizable gooseneck hitches on the market. This fifth wheel installation kit actually is the Turnoverball gooseneck hitch from B&W.

Gooseneck Specs:

  • Gross towing weight: 30,000 lbs
  • Vertical load limit: 7,500 lbs
  • Ball size: 2-5/16"

B&W Companion Installed in Turnoverball Gooseneck Hitch

With the B&W Turnoverball underbed gooseneck trailer hitch you get the best of both worlds. When you go to tow a gooseneck trailer, the Turnoverball creates a sturdy, dependable connection with your trailer. And when you're done towing, you can stow the ball upside down in the hitch to get full bed access and a clean appearance. When you're ready to tow your fifth wheel trailer, just install the Companion in the ball hole in place of the gooseneck ball and lock the post in place using the built-in handle. You can remove the fifth wheel when you're done towing, leaving your truck bed open once again.

Simple, Custom Installation

This kit is custom designed for your vehicle. The mounting brackets bolt to existing holes in your truck's frame. While some modification is required - you will need to cut a 4" diameter hole in your bed for the hitch ball and drill holes for the built-in safety chain loops - there is no need to weld onto or to drill into your frame.

Once you have the brackets and center section installed, set up the operating handle. This handle is designed to be accessed from the rear driver's-side wheel well. On the end of the handle is the heavy-duty steel pin that secures the mounting post of the Companion (or the base of the gooseneck hitch ball).

  • B and W 5th Wheel Trailer Hitch fora 2014 Ford F-150 Super Crew

If you have a long bed you would use the same installation kit but you would need the fixed version of the hitch, not the slider, # BWRVK3500-5W.

  • Fifth Wheel Hitch Recommendation for a 2007 Ford F150 Short Bed
    Since you have a short bed truck you are going to have use a fifth wheel hitch with a slider to make tight turns like what you will most likely be doing in the camping ground parking lot.

  • Adding Both a Gooseneck and 5th Wheel Trailer Hitch to a 2014 Ford F-150
    The gooseneck plate # RP30138 will not fit the under bed installation kit # RP30064 for your 2014 Ford F-150 but there are other ways to have both a gooseneck hitch and 5th wheel hitch. You can use the B&W gooseneck hitch # BWGNRK1104-5W. Then when you want to tow a 5th wheel trailer you can use companion hitch # BWRVK3500-5W for a long bed truck or # BWRVK3400-5W for the slider version for a 6-3/4 foot short bed truck. I have included links to videos for all 3 of these parts for you.

  • Hitch Receiver & 5th Wheel Towing Capacities for 2012 Ford F-150 Super Cab
    The best place to confirm your truck's towing capacity is in your owner's manual. The base 2012 F-150 is rated for a 5000-lb towing capacity unless equipped with the heavy-duty trailer towing package. Higher towing ratings may apply depending on whether you have 2WD or 4WD and depending on your truck's wheelbase. I suggest you check pages 272 and 273 of your owner's manual to find your exact towing capacity based on your specific truck's mix of equipment. Please see the linked image taken...

  • 5th Wheel Trailer Hitch for a 2011 Ford F-150 6-1/2 Foot Bed with Firestone Ride-Rite Air Bags
    If you are using Firestone Ride-Rite system # F2542 on your 2011 Ford F-150 short bed then you can install a B&W 5th wheel trailer hitch, # BWRVK3400-5W, using installation kit # BWGNRK1104-5W. This is because this particular air bag system is designed to fit the B&W install brackets. If you are using Firestone kit # F2525 then you will not be able to install the B&W hitch. But you should be able to install custom installation kit # RP50081-58 since it uses 4 smaller brackets as opposed...

  • Compatibility of Firestone Ride-Rite # F2525 Air Springs w/ Curt 5th Wheel Install Kit # C16300
    According to my Firestone representative, the # F2525 kit you have is not compatible with a fifth wheel bracket kit. As you can see in the photo I've provided, the # F2525 attaches to the outboard side of the frame members, which is the same footprint where the fifth wheel brackets would install. There are two alternatives. The least expensive option would be the Timbren # TFRTT1502D which you didn't seem really thrilled about. The other option would be to remove your existing # F2525...
