I love this hitch adapter. I mostly pull gooseneck trailer, but occasionally I need to pull a fifth wheel. Easy to get in and I haven't had any problems getting it back out when I was done with it.



- 16310
by:

The rails are well made. But on the heavy side I’m reluctant to pull it out. I would like them to stay put also, they tend to move around some with the B&W hitch.


Comments
As long as you do not have a B&W Patriot or a thick bed liner this should be compatible. I would just be sure that every fastener is tightened down and you should be good to go.

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

Fit like a glove. Dropped right in and I installed the 5th wheel hitch in no time. Heavy and well built.

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.

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.



- 16310
by:

Everything fits perfectly. I like having the option to switch between 5th wheel and gooseneck hitches by pulling one pin.



- 16310
by:

Received product 4 days after ordering with free shipping. Seems really well made. No noises or clunks when towing. It dropped right in to my b&w gooseneck and my Reese 5th wheel dropped directly into it. Good product.

this base rails provide easy installtion of your 5th wheel hitch into the bed of your trucl

Nice fit esay to set up, no issues and works with my 16k B&W Patriot 5th wheel hitch, no issues. A lot better option then a new B&W Companion hitch or reconfiguring the truck bed to remove the existing B&W gooseneck

I cannot not say enough about trailer. Always have had my back with price,knowledge, and the best customer service. I have the Curt X5 Adapter and love it. I have it coupled to the Q24 her hitch My tow vehicle is a 2013 GMC 3500 Dually 4WD and tow a 40' 18k 2012 Keystone Raptor

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.

Very helpful people to answer any questions my part got here in a fashionable time and install was easy. Recommend this company to anyone and everyone!

Items arrived intact in original packaging, hitch components are well built for heavy duty applications also arrived ahead of the projected date. UPS gave regular updates of travel location and delivery date.

Very very pleased, good solid steel. Mounted right up to my BW hitch and adapted to my Curt 20K fifth wheel hitch. No issues at all.

Nice fit, very well built. My 20000 lb Reese manual slider fit it perfect. Thanks



- 16310
by:

Perfect! Let's me use my Reese 5th wheel hitch that I have had for 15 years and three moves, FINALLY!! Both of my one ton trucks have B&w bed hitches, so I got two for one with the Curt adapter!


Comments
Works great, I had a Reese hitch left from my old 5th wheel and two pickups with the turnover ball in the bed. This is easy to install and solid when pulling. Just what I needed.

Really impressed with the quality of the Curt product. Worked out great, fitting my new to me 98 Dodge 3500. Thanks etrailer.

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.

Received it within the week I ordered it, customer service was great, fit beautifully.

etrailer ships faster than any other supplier! Thank you for the excellent service!!!

The product itself is great! Easy install into the B&W and a quick wiggle or two and my Reese hitch dropped right in. Very sturdy. Shipping beat their expected delivery by 2 days. The exterior box was a bit beat up, but the adapter was fine. Not even a scuff on the finish. etrailer.com has done right by me in all four of my major item purchases. Definitely recommend to others!!

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.

Took a bit of work removing pieces of the truck bed liner to get it in place, but it has worked wonderfully since then! We are "full time" 5th wheelers this year, and the hitch and adapter has been great.
