We just purchased and are awaiting delivery on a 2020 Durango Gold 356RLT. Our tow vehicle is a 2005 Duramax 2500 HD diesel with air bags on the rear axle. We are changing from a Keystone Laredo 5th wheel. I am interested in the flex air pin box. Is it worth the investment to change from the Rotaflex pin box to the flex air pin box? Thank you for any opinions. Heather
I changed out my standard pin box last year and purchased and installed a FlexAir pin box and will never go back. Totally changed the whole dynamics of pulling a fifth wheel. Very smooth ride and no chucking. The 5er just floats behind you. I traveled 6000 miles and never had a problem.
My Rotoflex pin box failed at approximately 15,000 miles. The rubber torsion spring broke loose and started to migrate rearward causing the actual.pin to jamb into the hitch from the odd angle it was riding at. Up until that point I had no issues. LCI replaced the Rotoflex pin box with an upgraded Trailair Air Ride pin box at no charge even though it was past warranty. I am stationary right now so I haven't has a chance to tow with the new king pin.
We had the Rotoflex pin box replaced before we left the lot with a MorRyde 18k pin box, very happy with such ...
Lots of owners have had no problems with the flex air pin boxes reading on different RV forms an really love them, we have just had MorRyde pin boxes on are last trailer an this one ... I guess it's like owning a truck, we have always had Fords so why change to a Chevy or Dodge, creature of habit but the MorRyde brand has treated us well an again from what I have read the Flex-Air is a good product an is well supported...
Happy camping an Safe Travels in your new digs on wheels
