Speaker 1: Today we're going to take a look at the Curt X5 fifth wheel base rail adapter plate for the easy earn double watt goose neck trailer hitch. It's part of the adapter Curt easy earn double lock goose neck hitch to work with a fifth wheel trailer hitch to meet your towing needs. The adapter plate attaches to the goose neck ball hole. If I tilt it here you can see the shank that goes into the ball hole and provides these rails that will let you mount almost any fifth wheel hitch. Again, it fits the Curt easy earn double lock goose neck hitches and will work with most standard above bed fifth wheel hitches by Curt, Draw Type, Hidden Hitch, Huskie, Reese and Valley.It's very fast, simple installation. Just drop this adapter into the ball hole in the goose neck hitch and lock it in place with the hitch handle.

This is a sturdy steel construction. It's a nice carbide black finish. Few specs on this. The gross towing weight capacity is 20,000 pounds and the tongue weight capacity is 4000 pounds. And one note on this part is bed liners and bed mats may affect the fit of this adapter, so trimming may be necessary.

But that should do it for the review on the Curt X5 fifth wheel base rail adapter plate for easier double lock goose neck trailer hitches.

Everything arrived in perfect condition. With a little trim of the bed liner the adapter fit perfectly as described. My Curt A-16 hitch looks great paired up with the gooseneck adapter. Ready to hit the road! 402615

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


I recently purchased a used '08 Ford F-350 with a B&S turnover gooseneck hitch. I wanted to use a Reese 16k hitch that I already own and put it in this truck without doing the typical bed rails to attach the fifth wheel hitch. I contacted Etrailer and they quickly identified the Curt X5 adapter to solve my issue. Ordered new adapter and in 3 days I had the unit and everything fit perfectly. This is the second time I have dealt with Etrailer in the last 6 months and I continue to be impressed with all aspects of this company. I'm glad I found Etrailer 6 months ago when I was looking for trailer hub and brake parts. I knew just who to turn to with my latest needs. Thanks Etrailer! 208661

Great. Works well to allow me to go from goose neck to fifth and back again with ease. Very satisfied!

Ordered Curt X5 Fifth Wheel Adapter for my B&W Square Shank Turnover Ball Hitch and received it in two days. Had it installed in my trucks in a matter of minutes. Just pulled out the ball and inserted the adapter, no holes to drill in my truck bed and simply unpin it and remove it to have full use of my bed. Love it! 192930

It is great! Just got back from a 4800 mile trip and unhooked my fifth wheel and pulled the pin and removed everything from my truck bed. The only way to go!

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


Received the Curt X5 B&W turnover ball adapter yesterday. Would have been easier to drop in with two people but I was able to do it myself. Dropped right in, and in less then 15 seconds it was dropped and locked. Saved me lots of install time on 5th wheel rails. Set my RBW lil' rocker hitch on and pulled my 10,000 lbs 32' 5th wheel across town without issue. I feel that this is probably the strongest way to go when running a 5th wheel to turnover ball adapter, and its only about $*** which is a fraction of the cost for those other weird complex adapters that side load or flex. Customer feedback was great with optimal response time on my questions. 266615

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


Nothing fancy, strictly utilitarian and simple. Built like a bomb shelter and shows no signs of wear. I pull a Keystone Laredo 298BH almost bi-monthly and this gives me the flexibility I need to switch hitch styles between trailers. If you need a completely flat bed for hauling then you still have it versus bolted on bed rails. Much safer than a 5er extension and doesn't void the warranty on your travel trailer if there is a failure. I shimmed mine off of the truck bed to take out the slop with 2 sections of round baler belting from a tractor supply store attached via industrial adhesive and it works beautifully. It weighs a lot so swap outs are a bit of a chore but i wouldn't want it to be built any lighter. Bravo on a great product 357271

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


After reading numerous favorable reviews on the goosseneck to 5th wheel adapter #16310 I decided to purchase one from etrailer.com. My entire experience has been truly outstanding. I ordered the adapter on Sunday night and Monday morning I received a phone call confirming my order and address. The order shipped on that same day and arrived on Thursday. I installed the adapter in my truck within minutes and installed my HUSKY slider hitch within minutes with absolutely no problems. I picked up my new 5th wheel and the adapter and hitch worked perfectly. I highly recommend etrailer.com and the Curt X5 Fith Wheel Adapter for B and W Square Shank Turner Ball Hitches-16310. 170741

I just wanted to say the people at etrailer are some of the best people to do business with. Me being someone who always seems to get broken or flawed items when i order online can with all honesty say i feel they went out of their way to make sure my adapter arrived in time for my trip and in excellent working order! I have looked thru their site and seen all the stuff they carry and if they have or can get it i will do business with nobody else. If you want a company that does business they way it's supposed to be done than you can't go wrong with these guys! Thank you so much and it's all my pleasure to give a 10star review.... 192401

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


Excellent product, well made and fits as it should on both sides. A device like this, to be worth making and selling, has to have certain assumptions as to fit and function. Curt has done a great job of giving the customer flexibility in fitting up. In my case the (turnover ball) pin went part way in and stuck tight. I thought that removing the rubber shims on the underside of the adapter would be too much downward movement, so, with 5th wheel hitch installed, I found some washboard road to drive on. Problem solved; pin works perfectly. By the way, I call this thing a "spider". After all it has 8 legs. 426799

This is just what I was looking for, already had Curt R5 slider hitch, put B&W hitch on new truck. Tried a gooseneck adapter, but too much flex. Went back to 5th wheel hitch. This adapter is built heavy, weighs over 100lbs by itself. I pull a 14,000lb toy hauler, with a F250 shortbed, needed the slider. I feel much safer with this product. Ordered from e.trailer, shipping was right on, only 3 days. 134542

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


I just purchased a used pickup that had a B&W square shank ball set up in it. I really was not looking forward to the headache of installing a rail kit, what with the drilling etc. that is required. I kept searching until I found this product. For a comparison: frame rail install with all drilling that's required, several hours; installing this, 30 seconds. It's definitely the way to go if you already have a gooseneck ball set up in your truck. I was also very impressed with how quickly the item arrived. I was expecting a week or so, instead it arrived in three days. I am very happy all the way around. 158746

Great product! Ive pulled a 42' to Hell and back not one problem. It is heavy, but it's very solid. My fifth wheel hitch fit straight in. Way cheaper than having to put rails in if you have a factory ball hitch in the bed. Its It's also nice that it's removable so you can haul furniture, or things that can't sit crooked ect. Great product, should last forever. Definitely would recommend 261579

Have a truck with a goose neck hitch but needed an adapter to haul a 5th wheel trailer. This hitch is very easy to use, fits well in my bed (truck bed is very banged up and uneven from years of demolition/ remodel work and fire wood hauling), and is quick to place and remove. The adapter lays flush enough in the truck bed that it wouldn't affect most loads or cargo (i.e. Lumber, mulch/bark, fire wood, etc.) My 5th wheel hitch (Reese) fits perfectly with the hitch. I am incredibly pleased with all aspects of this product. Worth the price for the ease of use. 262334

Fits perfectly into curt goose neck hitch. My reese 5th wheel hitch fits on the rails perfect. I haul dirt bikes in my truck so being able to take the rails out is perfect..... nothing in the way of loading or unloading 99283


Comments

Will the Curt gooseneck to 5th wheel rails adapter work with a Pro Series Slider 5th wheel? That is, will the slots match up?

-- comment by: Mike - 05/11/2014

Yes. The tab slot spacing is pretty universal amongst most manufacturers including Curt and Pro Series. Your Pro Series slider will drop right in to the the Curt X-5 adapter.

The X-5 is a heavy built, nicely finished adapter. It literally took me longer to open the box than to install it. I slipped it into the opening myself. I owned a Pro 15k which slipped right into the rails. I had assumed when I purchased this product (as it was advertised to fit a B&W turnover) that there was a built in offset to counter the typical 6" install towards the cab. After measuring my trailer it's appearant that a slider is now needed. It would be ausome if there was an option for an offset especially for the price. 336435

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


Heavy duty. But it does not drop into B & W under bed hitch far enough for the capture pin to engage the hole in the Curt adapter. I am not going to modify my spray in bed liner to solve this problem. Curt should make the hitch work without the need to modify a spray in liner. ( A larger hole in the Curt drop in shaft?) Maybe when I am able to drop the trailer onto the hitch it will engage the B & W under bed pin due to the extra weight. At this point I'm not satisfied . 345043

I recently purchased a 2015 Denali HD to pull our Rockwood 5th wheel. This truck had the B & W goose neck already installed. Instead of removing the hitch from the previous truck, I decided to try the B & W with the Curt X5 5th Wheel adapter. After reading the reviews, I was anxious to see if it fit as some said it did and others not. I ordered it on Wednesday and received it the following Monday. It was so easy to install and fit perfectly. Thanks etrailer. 424867

What a deal, much lower price then anybody else, extremely fast shipping! Just drop it in, set the hitch, good to go. When done, take out the hitch, take out the adapter and have a perfectly smooth bed for whatever. Appears to be heavily built, very solid and how much simpler can you get, drop it in the gooseneck hole, throw the lock lever and you're ready! Like everything else I've order from etrailer, top notch stuff at great prices! 420637

Managed to get my hands on a curt E16 5th wheel hitch and couldn’t be happier with the combination. The drop in weighs 100lbs and is honestly really easy to install. The hardest part is getting it from where it’s stored to the back of the truck. 460578

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


I use this on a 3500 Silverado which come with an original spray on bed liner. This makes my fifth wheel adapter very hard to hook to the goose-neck hitch. I virtually have to undo the main bolts and then torque them again after the adapter is hitched. Upon my complaint, I was told to simply cut out the bed-liner???? Imagine!!!! Once mounted, the fifth wheel hook up work just fine. I am lucky to own a pneumatic impact gun though.... 568126

Excellent product, good build quality, it didn't work for me as a drop in and use it but etrailer was willing to make it right. My fifth wheel hitch bolted right in with no issues. Excellent how all pieces can be removed leaving a flat bed surface. Do not expect this to fit in 2017 F250 with B&W turnover ball (bwgnrk1117) as it will not lock in place since the ridges in the truck bed are different height than previous year trucks. 389696

Excellent product that solved my issue of needing both a gooseneck & fifth wheel hitch in the same truck. Drops right in & fits perfect even with a spray in bedliner. Just towed our 20,000 lb toy hauler with it this past weekend- it performed flawlessly. It actually felt no different than our other truck with the fifth wheel rails bolted in, plus it can be removed & you can be back to pulling a gooseneck in minutes. 494852

I ordered the curt adapter for my already installed B&W turnover ball and it works just as advertised. I had a spray in bedliner which didn't cause any issues. When I contacted etrailer Chris was very helpful and knowledgeable. Any question she wasn't sure about was directed to a technician who was able to answer. The item was packed very well and arrived in near perfect condition. Overall excellent experience. 351504

5th wheel adapter plate fits perfect in ball socket. The hitch which I'am mounting to the adapter has a solid bottom, it will not allow the hitch to mount to the rails. I was wondering if you sold a 2" spacer kit # 46250 for a ts3 Trailer saver hitch? If so how much is it. Rubber Pads were put on backwards so the stuck to the box instead of hitch. can I get 4 pads?

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters


I was so happy to discover this adapter. I had to have a gooseneck hitch and wanted it to be hidden. I was dreading the fifth wheel rails sticking up in the bed again (bed replacement). This does the trick. Only reason for 4 starts is that it is a bit tight with no bedliner. Not even a spray in. But, I guess the maker has to build to a certain spec and not everyone would have a bedliner... 438660

etrailer priced matched to best the competition. The hitch was delivered a day earlier in great shape and ready to use. Exactly what I needed! Great job! The Curt 16310 hitch allows me the flexibility of using a B&W gooseneck hitch to pull a stock trailer. I can then install the 16310 hitch, drop my 5th wheel hitch on top and go camping.

Etrailer did a great job of shipping very very fast received in just three days. The X5 it's built very sturdy and it is very heavy it seems to be very strong. The only issue that could be with this product is when you use it with a B&W hitch it seems to set it a little deeper in the bed maybe about 6 inches behind Center axle. If you don't have a slider hitch this could be a problem 245646

Great product and easy to install. etrailer staff was great. Shipping was fast. One note: if your goose neck pin doesn't fully engage due to a spray in bedliner, connect up to your trailer and the weight of the trailer should allow the pin to fully engage. After my first trip the adapter settled enough and the pin engages easily without the trailer weight. 230906

Received product very quickly within 4 days with the free shipping option. The adapter dropped right in. The only issue I had is two of the small rubber pads came off the bottom of the adapter and we're stuck to the cardboard so in useable. I put the 5th wheel hitch on the rails and everything lined up except the two pins on the cab side will have to be hammered in. 209303

I think this is great very handy and easy to operate just drop it in and go. The one thing I found out when I first used mine was there is a only one way to put it in and pin it properly. I had to take it out and turn it 180 degrees and drop it in, then the pin went in all the way. It's a very tight fit and that's important to me. Great product! 475630

Works well with 5th wheel hitch. I was hoping to be able to remove adapter fairly easily to access flat bed when not using 5th wheel hitch, but that's not happening. It's a very tight fit in my gooseneck receiver, so not able to remove adapter very well. I'm disappointed in that, but otherwise pleased with your product. Thank you. 554188

Shank was too long. It bottomed out in the gooseneck hole an inch and a half at least before the rails touched the linex. Some modification was needed to make it work. Can't just drop it in and go. Glad I wasn't going camping the week it was delivered! Looks well built and the idea is good. Just needs to fit as advertised! 200398

Great product, fits perfectly and performs well. I have the B&W turn over ball hitch and considered the B&W 3500 5th wheel. I bought this instead, about $500 less expensive and used my existing 5th wheel hitch. No issues and saved the money. Caution lifting this piece, it is over 100lbs, highly recommend using two people. 196913

This is so much better than having the rails permanently in my truck. The installation went well. Having to cut the heat shield is one of those moments on a brand new truck but it needs to be done. I recommend getting a plug for the turnover ball. Winter salt will not be kind to the ball in the turned down position. 290262

The installation is clean with a small 4" cap when not towing. I was so happy with the product, I have purchased another C615-632 for my new truck also 473564

  • Comparing Curt X5 5th Wheel Base Rail Adapters and Compatibility with Draw-Tite Gooseneck
  • The differences between the Curt X5 adapters is what they will fit. X5 adapter # C16220 fits Curt EZr Double-Lock gooseneck hitches. And X5 adapter # C16210 fits Curt Double Lock, Flip and Store gooseneck hitches such as # C60720. The biggest difference to note is the shank from the bottom of the adapter is a different length. The # C16210 has a shank that is 4.41 inches long and the # C16220 has a shank that is 4.66 inches long. So the difference in the length also means the hole...

  • Recommended Curt Gooseneck and 5th Wheel Hitch for 2017 GMC 2500 HD Denali
  • For your 2017 GMC 2500 Denali, I recommend the Curt EZr Double Lock Underbed Gooseneck Trailer Hitch with Installation Kit - 30,000 lbs # C611-624 is a confirmed fit as is the Curt Double Lock, Flip and Store Underbed Gooseneck Hitch w/ Installation Kit - 30,000 lbs # C607-604. The only major difference between these two is the tongue weight rating of the Double Lock is 7500 lbs compared to the 6,000 lbs of The EZr Double Lock. The other difference is in the safety chain loop locations...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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.

  • Recommended 5th Wheel Hitch Rail Adapter or Custom Hitch for 2017 Nissan Titan XD
  • The Curt X5 5th-Wheel Base Rail Adapter Plate for EZr Double Lock Gooseneck Trailer Hitch # C16220 will not work on your 2017 Nissan Titan XD. Currently the only adapter compatible with your truck is the Demco 5th Wheel Rail Adapter # DM6200. This will allow you to use any standard sliding hitch for short bed, or fixed hitch for the 8 foot bed. Your capacity will be 21K maximum when using this rail adapter. Your other option is to use a hitch designed specifically for your factory...

  • 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. 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.

  • 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,...

  • Curt Fifth Wheel Hitch Recommendation to Fit 2015 GMC Sierra 2500 with Curt Gooseneck
  • Sounds like you have the Curt EZr gooseneck hitch part # C611-624 installed in your 2015 GMC Sierra 2500 short bed based on what you described. To install a slider gooseneck hitch you'll need an X5 adapter part # C16220 so that you have a set of rails for the hitch to install in. Once that's in place you could then install the Curt A16 5th Wheel Trailer Hitch w/ R16 Slider # C16521 that you referenced which would be a great choice.

  • Will Curt Q24 Fifth Wheel Hitch Work With Curt X-5 Adapter
  • The Curt X-5 Fifth Wheel Adapter, part # 16310 is designed to fit B And W Square Shank Turnover Ball Hitches. If you have the B And W installed in your vehicle, the X5 will work well for you. The weight capacity of this adapter is 20,000 lbs. If you have the Curt Double-Lock, Flip and Store gooseneck hitch, you would use the Curt X-5 Adapter, part # C16210. If you have a Curt EZr Double-Lock gooseneck hitch, the adapter you need is part # C16220. The Curt Q24 5th Wheel Trailer Hitch,...

  • What Gooseneck Hitches Work With Curt X5 5th Wheel Base Rails Adapter
  • We offer three X5 5th Wheel Base Rails Adapters. The X5 needed depends on the gooseneck system installed on the truck. If you have a Curt Double Lock, Flip or Store gooseneck hitch the X5 adapter you need is part # C16210. If you a B&W standard center Turnoverball hitch the adapter you need is part # 16310, and if you have the Curt EZr Double-Lock gooseneck hitch then the adapter that will work with that is part # C16220. Installing any of these adapters will be compatible with...

  • Available Curt X5 5th Wheel Hitch Adapters That Allow Use of Industry-Standard 5th Wheel Hitch
  • Curt offers several versions of their X5 5th wheel hitch adapter that lets you install an industry-standard 5th wheel hitch in a truck that does not have standard base rails. Part # 16310 fits into a B&W gooseneck hitch, part # C16210 fits a Curt Double Lock Gooseneck and part # C16220 fits the Curt EZr Double Lock gooseneck hitch.

  • How to Tell the Difference Between the Curt Double Lock & EZr Gooseneck Hitch
  • If you could send me a picture of the gooseneck hitch you have installed in your 2017 GMC Sierra 2500 then I would be able to make a more educated guess but based on your description you have the Curt Double Lock Gooseneck Hitch part # C607-604 and the correct adapter would indeed be part # C16210. However, if the gooseneck hitch was installed at the dealer then you would have had the Curt EZr Gooseneck Hitch part # C611-624 and the correct adapter would be part # C16220. I have attached...

  • Gooseneck Hitch Adapter for 5th Wheel Trailer Connection on 2017 Ram 3500 Short Bed
  • The B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400 is only compatible with the B&W Turnoverball Gooseneck Hitches. If you have a different gooseneck hitch, then there are other potential options. For instance, the Curt X5 5th Wheel Base Rails Adapter for Curt Double Lock Gooseneck Trailer Hitches - 20,000 lbs # C16210 will work on that gooseneck to give you rails so you can add a sliding hitch. Curt also has an adapter option for their EZr double lock...

  • 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.

  • How to Install B and W Slider Fifth Wheel Hitch in Bed of 2009 Chevy Silverado
  • Without knowing for sure what gooseneck hitch you have I can't really say for certain if there's a way to use a B and W Slider hitch with it. If you had a Curt EZr gooseneck hitch which uses a round ball shank hole you could use the Curt X5 adapter part # C16220 which would allow you to use the B and W Patriot Slider part # BWRVK3270 that you referenced. But if you are dead set on using a Companion Slider part # BWRVK3400 you'd have to remove the hitch you have now and install a Turnoverball...

  • Compatibility of Pull-Rite 5th Wheel Hitch with Curt X5 Adapters
  • Curt's X5 5th wheel adapters, parts # C16220, # 16310 and # C16210, all provide the equivalent of industry-standard 5th wheel base rails to allow installing a 5th wheel hitch in a truck that has a gooseneck hitch installed. These three adapters are designed for specific applications; for example part # 16310 installs into the square-shank hitch ball hole of a B&W Turnoverball gooseneck hitch. All versions are shown on the linked page. If your Pull-Rite hitch has the ISR designation in...

  • Recommended 20K 5th Wheel Hitch to Fit Curt X5 Adapter w/Round Shank on a 2013 GMC Sierra
  • I have a solution for you but, B&W doesn't make a 20K Fifth Wheel for above bed rails your Curt X5 adapter provides. 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 Pro Series # PS30119 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 Pro Series...
