Do you have a question about this Gooseneck and Fifth Wheel Adapter?

• Recommended System To Tow A Gooseneck Or Fifth Wheel Trailer With 2016 Chevrolet Silverado 3500
  
• I do have a system that lets you tow either a gooseneck trailer or a fifth wheel. First, you will need the EZr Double Lock Underbed Gooseneck Trailer Hitch, part # C611-624. This system gives you a gooseneck hitch in the bed of your truck with a 30,000-lb capacity. You would then need an adapter, part # C16220 to install in the gooseneck ball opening in the bed of the truck. This gives you base rails for a fifth wheel hitch like part # C16245. I recommend a different system for...

• What is the Difference Between the Curt X5 Gooseneck to 5th Wheel Adapters
  
• The differences between the Curt X5 adapters is what they will fit. X5 adapter # C16220 fits Curt EZr Double-Lock gooseneck hitches such as # C612-647. And X5 adapter # C16210 fits Curt Double Lock, Flip and Store gooseneck hitches such as # C60720. There is also an X5 adapter, # 16310, that fits B&W gooseneck hitches. So basically if you have any of the above mentioned gooseneck hitches you can use the appropriate X5 adapter.

• Curt X5 Adapter for B&W Gooseneck Trailer Hitch
  
• Fora B&W Turnover gooseneck hitch with a square opening, you will need Curt X5 adapter, # 16310, instead of adapter # C16220. Another option instead of using an adpater and then a separate 5th wheel trailer hitch is to use the B&W Companion hitch, # BWRVK3500 for a fixed version or # BWRVK3400 for the slider version. I have linked videos for each of these hitches for you.

• How to Tell Difference Between Curt EZr and Double Lock Gooseneck Hitch
  
• Easiest way to tell which gooseneck hitch you have is by looking at the safety cable loops. If they are about as wide as the gooseneck ball hole and are centered with the ball hole it's an EZr, if the safety chain loops are a smaller and offset then it's a double lock. Take a look at the pictures of the EZR part # C611-624 and the # C607-604 and compare your safety chain setup to both of these. Let me know which yours matches and we can go from there. The part # C16210 is for the...

• Can a 5th Wheel Install Kit be Installed on 2013 GMC Sierra w/Curt Gooseneck Hitch Already Installed
  
• In order to install a different 5th wheel or gooseneck installation kit in your 2013 GMC Sierra the old one, C611-605, would have to be completely removed. The alternative is to keep the gooseneck hitch you have and use the X5 adapter, # C16220, and a hitch that fits in above the bed 5th wheel rails such as the Curt Q24, # C16546. I have linked a video review of this hitch for you.

• Availability of 5th Wheel to Gooseneck Adapter That Clamps to Gooseneck Hitch Ball
  
• The Curt X5 Fifth Wheel Adapter you mentioned, part # 16310 isn't designed to attach directly to a gooseneck ball. The square shank of the adapter is meant to fit into the square hole where the ball would install into a B&W Turnover Ball Gooseneck Hitch. I've linked the instructions for you. If you currently have a B&W Turnover Ball Gooseneck Hitch, the # 16310 adapter would work great for you. You'd release and remove the gooseneck ball and insert the shank of the adapter in its place,...

• Should there be 1 Inch of Play After Installing the Curt X5 Adapter
  
• First, make sure that when using the Curt X5 adapter, # C16220, that you are putting it into a compatible Curt Gooseneck trailer hitch (Curt EZr double-lock gooseneck hitches). It is not designed to be used with any other hitch. If the locking pins are positioned properly and you get an inch of vertical movement then something is wrong and you would not want to use the adapter until the problem is fixed. One inch is way too much movement. The X5 adapter should only move vertically about...

• Is there an Advantage to Going with the Curt A205th Wheel Hitch over the A16 for a 2016 GMC Sierra
  
• I would not say that the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider - Dual Jaw - 20,000 lbs Item # C16541 functions differently or smoother compared to the A16 # C16521. The advantage of going with the 20K hitch though is that if you ever plan on towing anything heavier than 16K you will be ready! The X5 adapter for your Curt EZr gooseneck hitch is # C16220.

• Does Curt X5 5th-Wheel Base Rail Adapter C16220 Fit Curt Gooseneck and How Does it Prevent Twisting
  
• The Curt X5 5th-Wheel Base Rail Adapter Plate # C16220 will fit your truck bed that has a Curt gooseneck hitch. What keeps the shank from twisting in the ball opening is the pin that inserts through the adapter. It's the same pin that holds the gooseneck ball in the hitch.

It sounds like you have the Curt underbed rails since the round shanked Curt X5 adapter # C16210 or # C16220 fit into it that rounded shank. I have two recommended options for you. The Reese 20K Titan # RP30867 or the Demco 21K Hijacker # DM6076P-21K. The Curt adapter does have a 20K limit so you will have to abide by your lowest rated item in your setup. The Titan...

• Will the Curt Q24 5th Wheel Trailer Hitch Fit the X5 Adapter # C16220
  
• Yes, a Curt Q24 hitch, # C16245, will fit the X5 adapter # C16220. But the adapter is limited to 20,000 pounds gross trailer weight so you are limited to 20K even though the hitch is rated higher. And if the tow vehicle is rated less than 20K then you would go by that rating. Always go by the lowest rated component in the system.
