Got here on time, some assembly fit perfectly. Satisfied Customer

It works great


Easy to remove and re-install.
down side is the above bed box vs the rail system adds an extra height which elevates the nose of our 38 foot 5th wheel TH above level for hauling.

another point you should know if you do purchase this item make sure that you inspect the hardware carefully - really carefully !

the lock handles x 2 times had slag in the threads.
with the assistance of etrailer Reese sent me a replacement set which were worse than the first ones. Reese then paid me to get the threads cleaned out.



new 2022 F250 truck is 2 inches lower than the 2018 F250. the trailer sits lower

2013 Ford F-250 Super Duty

Upgraded my 2013 F250 to a new 2024 F350 with puck system and needed to convert an R16 5'th wheel hitch with slider from rail system. This item worked perfectly. It is solid in the bed of the truck. I have already towed for 2 trips, and so far it works great.

2016 Ford F-350 Super Duty

We ordered this for our 2016 Ford F-350. The part comes unassembled, but with instructions that are easy to follow. I did have to adjust after assembly to fit our truck properly. ( The instructions state you may have to adjust ). If you get this I will recommend that you get the wrench, it would have made the adjustments easier. My hitch dropped right in the slots and pinned right in place. NOTE: the pins for the hitch are not included, so order them if you do not have them. The adapter does not rest on the bed, only on the FORD under bed adapter.

Everything is working like it is supposed to. I do not see excessive rusting, the paint is holding well.

2019 Ford F-250 Super Duty

This was the perfect fit for a 2019 F250. Our other truck was in the shop and we needed to haul the toy hauler with our new truck. etrailer customer service was great because we needed this next day shipping to complete our camping trip. The F250 is a short bed and no slider hitch but there was still plenty of clearance to the cab.



This product is great I use it in a 2019 and a 2016 Super Duty.

2019 Ford F-250 Super Duty

The adapter came as expected. It went together real fast. Keep everything loose when you insert same in the vehicle. You will have to adjust the four points, that is the nature of the beast. After the adjustment, the adapter fit fine. My Reese 16,000 hitch fit just fine.

Used it on a month long RV trip. did just fine


Installed slider hitch with quick removal base. Also fit's and works great.



Do you have trouble getting the slider to latch with the camper attached?

Ford F-350 Super Duty

My new F350 didn't have the under bed 5th wheel mount and I didn't want to use the rails that bolt across the bed. I bought the Reese under bed parts, Reese adapter, new legs for the hitch and a bed mat and installed it myself. I drilled through the dimples in the bed, bolted in the under bed parts and everything lined up nice. Since I went from a short bed to a long bed I didn't need the slider legs so I replaced them with fixed legs. When the hitch and adapter are out of the bed, nothing is in the way on the floor. I like it.


Thanks for the help with getting the adapter. This is how the job ended up with the under bed mount and adapter to the standard fifth wheel.

Ron G.


The adapter has been working great. Gives me the flat floor I wanted and I didnt have to buy a different fifth wheel.

2015 Ford F-350 Super Duty

Just installed the Reese Rail Adapter in my 2015 Ford F-350. It fits the factory 5th wheel prep package perfectly. The only issue I had was with fine tuning the latches (trial and error) but even so, this was a breeze to install (15-20 minutes). As always the shipping is FAST! I had the kit at my door two days after ordering.

2012 Ford F-250 and F-350 Super Duty

Great product, great price. Easy to assemble, and fit right into my factory Ford puck system as it should. Simplified my delima of what to do with my hitch after trading in my old truck, and refitting to my new truck.

2018 Ford F-350 Super Duty

We had our dealer install the RP30156. They were more than satisfied with the product. We had a 2014 F350 and installed this to make our Reese 5th wheel hitch work in our 2018 F350.


very pleased with the product. went together with easy installation and works great. very knowledgeable people I worked with. Great job with all the help.


Was easy to put together. Works excellent with my Reese Pro 15K hutch that I had in my 2017 F-250 that used the rails instead. I lowered the head on my hitch 1 and 1/2 inches when done to make up for the difference in height between using the rails and now the adapter puck system. This set up works great because when I take it out, it will be in 3 pieces that I can lift and move myself. I ordered on Sunday and had it Wednesday. This was a great option for my 2021 F-250 with the puck system. Buy buying this I probably saved $1,400 or more by not having to buy a new slider hitch.

2012 Ford F-350 Super Duty

Very easy to install, I didn't curse or throw a tool putting it together!
It really looks good with my old hitch in my new 2012 F-350 Lariat.
I haven't towed my RV as of yet, but I will let y'all know how that goes when we go camping next weekend. Attached are some pics.

2008 Chevrolet Silverado

Good product.
Easy build easy install.
you might want to offer the 1.5 inch socket with the purchase. They r a bit hard to come by.
Old hitch an easy fit.

2017 Ford F-350 Super Duty

Reese's Under Rail Adapter RP30156 is very easy to assemble and to install. Instructions provided are well written reducing the assemble time to les than five minutes. Installation took longer due to the snug fit between the trucks underbed rails and the adapter's pins.

Etrailer's delivery time is outstanding as well as their customer support team. They were very helpful in identifying the correct adapter match.


I installed this adapter in my 2019 F-350 Super Duty Long bed. I won’t kid you, you need some patience when it comes to adjusting it to fit your truck. Each mount hole seemed to be at a different height thanks to Ford. But it took all of about 20 mins to assemble and install. Fits great once you set the depth adjustments. Will see how it does towing this afternoon.

Ford F-250 Super Duty

I recently purchased an F250 with the puck system. This drops right in easily and works great with my 5th wheel Reese hitch.

2017 Ford F-350 Super Duty

Great Price, Fast free Shipping, Phone ordered and etrailer was excellent with fitment applications.
Ordered this for my 2017 F-350 which has the Ford 5th wheel prep package. It assembles easy with clear instructions and tips for mounting. Sturdy, strong and durable. Easy to remove when not towing. Great product from the great people at etrailer. Saved me the money to replace my entire 5th wheel hitch. I kept my Reese 16K hitch which mounts to this adapter. Thanks etrailer!!!

Product works great a year later.


I purchased a Reese Elite Series Underbed Rail Adapter for Standard 5th Wheel Trailer Hitches to adapt my old 5th wheel hitch to my new Ford truck. It arrived promptly after ordering, assembled easily, and works great. It was a great reasonably priced alternative to a $1000+ new hitch made for the under bed rail system in the new Ford trucks. Very pleased with the product and with etrailer.

Fits like a glove about 15min to assemb le


It was hard to tell from the pictures but this item uses the handles to rotate the locking clevis and is as easily removable as the OEM equipment! The fit was fantastic and assembly only took about 15 minutes. Big savings being able to continue using my Pro series 15k.

2018 Ford F-250 Super Duty

I received my Reese hitch frame using the 3 day shipping. It took around 1 hour to assemble. It was easy to assemble after watching the you tube video plus reading the paperwork that came with it.


Received the 5th wheel adapter on time .
about 15 minutes to assembly, then it took about 15 more minutes to adjust . My husky 5th wheel slider fit perfect .Thank you so much.
