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.

Great product, so easy to install and works great. 400983
Works great. The fifth wheel adapter has been used to tow my 19,000 gvw 5th wheel trailer from Wisconsin to Texas back and forth for 2 years.

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
The only problem i have had Is that I noticed the bracket dented my truck bed. ie: front to back pressure allows the rocking of the bracket, therefore putting a dent in the bed of the truck. 570068

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

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

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

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.

Review from a similar Curt X5 in Gooseneck and Fifth Wheel Adapters
Same issue as everyone else. Spray in bed liner made for a hard way to go. Never the less it is in and working will find out more after the maiden voyage next weekend. Already suggested it to a friend. 403344
This product is working great after a year. It is not so bad removing when I need the whole bed for hauling finish is very durable and has held up great thus far. As I said before I have shown it to a friend that was thinking about going the fifth wheel route for his own camper. Using it with a Reese slider haven a few issues with binding not sure if it is hitch related or from the adaptor moving. Movement is the same as any other receiver and hitch setup would be so it is not that much.

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

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

Love my Curt C615-632 under bed rail kit, and Curt C16210 5th Wheel adapter. This is easy to use, and I can maximize the use of my box when not towing. 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

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

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

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