Hannah did an excellent job of working with me to find the correct upgrades for my towing system. 5 stars got her. Tge package arrived with the king pin poking through the box and having deep scratches. I think it will function ok. 3 stars for those handling shipments and deliveries.

Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs
This item arrived much faster than etrailer said it would. It came by truck, and the freight company driver was very nice and made sure I opened the box before he left. I installed it myself with some help from my 15 year old son. We used our forklift tractor attachment to put it in place. The Curt Flex Air totally changed the experience of pulling our 5er. It eliminates most of the chucking, and acts like shocks on a car, so ride returns to normal immediately after a bump in the road...which the Flex Air absorbs most of.
Changed out my old pin box for a Curt Flex Air pin box. This one seems to be very heavily built and should last for years to come. Haven’t had a chance to pull it yesterday but am sure it will pull and perform great. Thank you etrailer for another great shopping experience.

MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert 1621 and 1621HD
We used to have a lot of slop with our hitch and that has lessened immensely since our purchase of the MORryde pin box.
Product was received as expected. Installation went very well. I am eager to try it out this week on the road!

MORryde Cushioned 5th Wheel Pin Box for Up to 11.5K Trailers w/ Lippert 1621 and 1621HD
Very great product, took the chucking and jerking out when towing my fifth wheel, would recommend it to anyone, wish I would have gotten it years ago.
Dramatically reduced chucking as hoped. There is more start/stop slop than I had expected but I'm guessing that is due to my trailer being at the top of the weight rating for the rubber block. I need to put a camera on it to verify my theory. All in all a huge improvement.

Curt Air Ride 5th Wheel Pin Box - Lippert 1621 & 1621HD - 21,000 lbs
the fit was perfert. as you can see from the pictures is attached, i drilled a hole in the top to drain water that collects. i fabercated a cover to fit over the opening.
Best upgrade to the 5th wheel you can do. Our first cross country trip and I-40 beat the snot out of us on all the bridge transitions with the stock pin box. Immediately ordered this unit and now it’s like the trailer is floating behind us. I run 65 psi in the airbag. Solid unit and easy installation.

Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs
Freight co delivery estimated for Friday, arrived today. (Tuesday). Borrowed a tractor, dropped the old and lifted this monster into place. 12- 15/16 bolts (originally) 18 hole mount. Not sure if the height is correct for the bed, but will adjust it down if after the rubber bumper is inflated, if it doesn’t sit level. The bolt pattern was correct. better get help! From dropping the MFG lippert, to getting the thing lifted an bolts snugged up, about 45min. Will take a bit longer to attach the deadman switch and electrical box. Well crafted, definitely heavy. This should save my truck n RV from porpoising damage as I’m going over Bridges and bad roads.
We're so anxious to try out our new Curt TrailAir. Installation went smoothly, it looks great. We can hardly wait to experience the ride!

Curt Rota-Flex 5th Wheel Pin Box - Lippert 1116 - 19,000 lbs
It's a great pinbox. Really helped with chucking and compatible with my Demco sliding hitch. Also no issues with delivery, was helped by Pam and Jessie. They are awesome people to work with.
I have had many coach's with this hitch, that is why I am changing out the one currently in the coach to this. UPS delivery sucks. Box was misrouted to another terminal after arriving at the facility near me. Caused an extra day's delay in delivery. When box did finally arrive it was virtually destroyed and driver claimed box showed up open and that they had to retape it this morning ING before delivering it.

Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs
My wife and I are very pleased with our purchase of this product. We have taken numerous trips with our rig since installing it and what a difference it has made from the standard basic pin box. We no longer feel any chucking from starting off and stopping when towing our trailer. I figured it would definitely reduce it but it eliminated it completely. We tow with a one ton F350 long bed SRW and a B&W hitch. In my opinion It is not a DIY installation because of the sheer weight of the product otherwise I think that it would be. It is not a complicated item to install its just super heavy. In addition to my praise of this product, I would like to recommend the addition of grade eight hardware to be included with the product for installation. I think a few dollars more for the price should more than cover that cost. When it comes down to it the grade five hardware is sub standard for such a massive object in my opinion. It is supporting not only the weight of the pin box but the torque under load as well so for the purpose of safety, which is why we purchased it in the first place the hardware has to come off anyway to take off the old pin box. So why not replace it at the same time. My two cents worth anyway. I would definitely recommend this product to others who are looking to eliminate the chucking felt under a standard fifth wheel pin box.
Well, The hitch was to be delivered on the 23rd. Tforce the company you chose to deliver is located in the Philippines and after speaking to 5 different NON English employees I gave up. So I called the Tforce in Fontana Ca where the hitch is now. NO One answers the phone then after 30+ attempts a female answered and before I could complete my request she transferred my call to an empty line.

Trailair Air Ride 5th Wheel Pin Box - Lippert 0719 - 18,000 lbs
I just completed a 2800 mile trip after installing the Trail Air Air Ride pin box on my Solitude 5th wheel. I was able to install it myself from the bed of my pickup using a hydraulic bottle jack to lift it into position. I previously made the same trip with the factory installed MORryde Cushioned Pin Box and the Trail Air provides a greatly improved ride. With the MORryde, I encountered several sections of concrete highway that set up a front-to-back oscillation which persisted across many miles. I didn't have that issue with the Trail Air. I didn't order the Flex Air model that also included the flexible block because I was concerned the added height of that pin box would have been a problem. However, after installing the non-flex Trail Air I've found that the other one would have also worked out if I lowered my truck hitch an inch or two. Also worth noting, this pin box is four inches shorter than the 1621 MORryde it replaced. However with a long bed truck I have no clearance issues and can still lower the tailgate when hitched up.
I'm pleased with the pin box. Put it on my 5th. wheel. The airbag gives us a better ride than any other pin box. Its a great product.

MORryde Cushioned 5th Wheel Pin Box for 11.5K to 14K Trailers w/ Lippert 1621 and 1621HD
So far this is a welcome upgrade. Took it on a short trip over some rough road that normally triggers chucking on my F-250. This pinbox prevented it which was a welcome change. I’m looking forward to some longer trips. Installation was straightforward. Removed the old pinbox which was fairly easy. Installing the new pinbox would’ve been a challenge had my buddy not had a forklift attachment for his tractor. I don’t know the exact difference in weight between the old Lippert pinbox and the new Moryde, but it is substantially heavier. I’d say 2 people muscling and one to install the hardware would still be a challenge. Forklift or similar is the way to go. Also, the new pinbox doesn’t come with new hardware. Got to use your old or make a trip to Lowe’s/Home Depot. All and all I’m happy with the upgrade, but I thought it was pricey and don’t like the additional weight.
This cushioned pin box is definitely worth the upgrade. Chucking is greatly reduced (There's no getting totally away from it) and the frequency of the chucking is tempered making the ride much more pleasant. There are times when you forget your towing it's so smooth on decent stretches of road. Delivery was quick (3 days early as a matter of fact) and driver dropped it in my garage. Plus the fitment was perfect, bolted on with no problem. Entire experience was good !!

Curt Flex Air 5th Wheel Pin Box - Lippert Rhino - 21,000 lbs
Delivered intact.
Replaced Rhino with this unit on my Cedar Creek 311RL. It was straight forward and simple, but not easy for this old man to do it solo. Used the tailgate as my shop. Stuck the back up in the air and drove back to insert into the bracket. I then used the levelor on the trailer to line up 2 of the holes to insert the first bolts. I used a car jack near the pin to raise the 230 pound box into line up position to insert the other 8 bolts. Torqued it down and aired it up, then test drove it. Rides like a dream. Much softer on those in the tow vehicle and I assume on the fifth wheel itself. Service from etrailer was good. The advice and recommendations for my specific rig was a little off. But I was able to do research myself. Shipping was timely. Over all another successful etrailer transaction. Thanks to everyone.

MORryde Cushioned 5th Wheel Pin Box for 11K to 14K Trailers w/ Lippert Rhino
I ordered this for my Grand Design 337 5th wheel to help reduce the chucking. I will start this with the order. The Pin Box arrived in a very beat up box. After examining the unit I found that one of the bolt fins was bent about 1" inward, the carrier must have dropped this from a truck. I called E-Trailer support and spoke with a very nice gentleman who took my info and said this does happen occasionally. He set up an advance replacement and prepaid return which shipped 2 days later. The new one arrived in good shape. I installed the unit today. I am extremely surprised how easy it went replacing the King Pin box. The MORryde box is heavy, using the bed of the truck and some 6x6's I got it the right height and really easy. I found cleaning the bit of rust the housing that the MORryde sits in and a little WD40 made this easier. I have not connected to the hitch and pulled the camper yet but have heard great things about this unit. I have the PullRite Auto Slide hitch so I had to install the adaptor as well. Many thinks to Etrailer for taking care the shipping issue and getting me a working unit, well done.
I received the package. Came boxed up. Fortunately I think all the parts are still there, even though the box has a big hole in it. Items are still in good shape.
What our customers are saying:
"WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!"
