Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs
I have used my Flex Air for over one year and put around 3000 miles on it. I purchased this for one reason to reduce bucking when I it bumps in the road. I can safely say that it has virtually eliminated the bucking. It has also made the ride a lot smoother. I would highly recommend the Flex air. I did my own install of this product by my self. My rig 2018 Toyota Tundra with a Husky 16 KW Hitch 2017 KZ Durango 30 ft.
The product that I ordered was what I received the person I talked to was very noligable and helpful Thanks

Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs
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.
No bucking and jerking has made for enjoyable RV experience this year. One of the best investments I've made in our RV. prompt handling and shipping from etrailer made it even better!

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.

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 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.
