Adapters for Towing a 5th Wheel Trailer with a Gooseneck Hitch
1. 5th-wheel adapter that replaces the trailer pin box
Most secure option Doesn't cause additional stress in either the trailer frame or hitch Creates more of a permanent solution Leaves your truck bed open for other uses Made to fit specific pin boxes
2. Another excellent option is a 5th-wheel adapter that installs in the ball hole of the gooseneck hitch
Doesn't require modification of trailer Provides a good solution for frequent switching between trailer types Great solution if you have to tow multiple trailer types with the same vehicle Fifth-wheel hitch is easily removed when you need to haul cargo in the truck bed
3. Adapters that Attach to a Gooseneck Ball in the Truck Bed
Attaches to underbed gooseneck ball in the truck bed Hitch height is adjustable One of the lightest hitch options available
4. Adapters that Attach to the Fifth-Wheel Trailer King Plate
The pin box and king pin DO NOT have to be removed Adapters can be heavy - an extra set of hands will help with installation Not all trailers can use this type of adapter - confirm with the trailer manufacturer Some manufacturers recommend that their adapters not be used with pin boxes over a certain length (always check for maximum recommended pin box length) Works well as a temporary solution Can cause stress in the trailer frame and hitch
Offset Adapters for Increased Clearance
Determining the Correct Height for Your Adapter
Back your truck into position as if you were hooking up your fifth-wheel trailer, making sure that the truck and trailer are level Measure from the king pin plate down to the top of the ball in the bed of your truck The measurement you get is the height of the adapter you will need

Thanks for any help.

When you say it came with "fifth wheel package" do you mean it has puck system? This will have 5 holes in the bed for quick install and removal of some fifth wheel hitches.
There are quite a few parts numbered 3300 in the B&W line. Did you friend have it on a Chevy? Can you tell me some more about the base of the hitch? Maybe a pic?

@LesD Yes my truck has a five hole system. I can tell you on the hitch it says Husky 26K. If you can send me your email I can send a pic or 2 on the hitch. I am looking to buy the part that will fit the 5 hole system. I cant figure out how to add a pic in here. The base of the hitch has 2 bars around 2 ft long which has notches in it. This bar has notches where the hitch attaches to it. I definitely need the part or bracket that attaches to the 5 holes in the bed. I am hoping I would be able to attach the hitch to the new bracket. Trying not to have to buy a new hitch...The previous owner had the hitch pinned with clips to the bars and the bars where bolted to the bed of his truck. He had an older Chevy. I really appreciate your time and getting back with me.
Thank you
Jim

I bought a newmar 5th wheel 35 foot has a custom hitch , need to know what type hitch I need, the guy I bought Rv from had a slide hitch punted up 6-12 in higher than bed on a custom made box that goose hitch was mounted on , some issue with his truck bed wasn’t steady enough for the weight of Rv so has custom hitch made looks like a pipe was welded to the outer hitch on goose neck then hooks to the goose nec hitch in pickup , not sure how it worked but he said had it especially for this Rv , he had Chevy 2500 2010 single cab , not really heavy enough for weight of Rv , but he said it pulled it fine after getting going . So I’m getting hd2500 Chevy with 6 in lift it taller than my hitch so what do you suggest without having to change it all to make it work , don’t haul it unless I move locations of need to travel for several weeks , Need a cheap solution

@Tanya I would not use anything that is "custom" made." I am initially concerned about towing with a truck with a lift kit as many times that causes clearance issues.
What trailer Newmar, model, and year is your trailer? Has it had any thing custom done to the trailer suspension?
What year is your Chevy 2500? What length bed? Guessing since pervious owner had a slider it was not 8 foot.
What pin box is on the trailer? What brand, model and bolt pattern. This will be expressed as a four digit number on the pin box.

I am purchasing a 2022 Toyota Tundra and would like to know what model underbed gooseneck hitch will fit. I currently have one in my 2011 tundra but can't seem to find one for the new Toyota. Please help!!!!!!!

The suppliers have not made hitches of any kind for the '22 Tundra yet. Check back with me in a few months.

@RobertM it's a Tundra, that's NOT enough truck to worry about pissing away money on a gooseneck or 5th wheel, you don't have enough ass in a Toyota to control or stop what you're trying to pull. Just because you can get the weight moving dosen't mean you have the means to control it and if your asking questions that says you shouldn't be trying to even own or purchase anything larger than a pop up camper, that's a good area to start with!

@RobertM I suggest that you review your owners manual, and then look at the stickers in the drivers door jamb to learn exactly how many pounds you can tow. Please carefully work out the math, and then plan at least 20% cushion.
The Tundra's towing capacity will be 8,000 to 12,000 pounds depending on how it is equipped.
I have attached a document called, "How Much Trailer Can I really Tow?" I suggest you fully understand this before making any purchases.
You also need to look at cargo capacity. A fifth wheel trailer can drop a lot of weight into your truck bed.

I have a 2016 RAM 3500 with a cylindrical (or round) mount for a goose neck ball (OEM) Is there an adapter to use that kind of mounting system with a 5th wheel hitch? B&W companion needs a square mounting hole.
