![]() ![]() BTW, Heartland is installing "The Isolator" on some of their Landmarks now. I could not feel any difference in the ride compared to a solid pin box. I also once pulled a 35 foot Potomac from Elkhart to Monroe, NC, that had "The Isolator" brand of air ride pin box installed and I was very disappointed with it. I have driven some of these same interstates with trailers that had air ride pin boxes and I honestly could not feel much improvement in the longitudinal jerking. I have a 36 foot fiver and I have pulled it to Colorado and back three times and it just beats me to death on the rough interstates such as the WV Turnpike, some places in KY, IN, and IL where they have those giant cracks between the segments of pavement. My biggest irritation with the ride in the truck has always been the fore and aft (longitudinal) jerking or "chucking" as some call it. In fact, Racerguy stated above, "When we arrive at our site everything is still in place." And I think he is talking about the inside of the trailer. You can watch the rear view mirror and see it flexing in the vertical axis and understand that it must be providing a better ride in the front end of the trailer. I could not tell that the air ride pin box provided any significant improvement in the ride in the truck. Later, I pulled a Landmark that had both the Mor/ryde suspension and a Trailair pin box. I was very impressed with how much the ride in the truck was improved. The ride in the truck was much smoother because the suspension absorbed the vertical bumps so the trailer did not transfer as much bumping to the truck as one without the Mor/ryde suspension. The first Landmark trailer I pulled had the Mor/ryde suspension but did not have a Trailair pinbox. I will assume what you all are talking about is the "air ride pin box" and try to share some experience I have had with them. ![]() An "air ride hitch" is something like the "Trailer Saver" or "Easy Rider" hitches that mount in the back of your truck and provide air cushion dampening on both the vertical and longitudinal axes. The original question asked about "Trail Air" and then said, "air ride hitch." Then some responders also said they have an "air ride hitch." Just to clarify, Trailair does not make an "air ride hitch." They make an "air ride pin box coupler." They also make the "Center Point Suspension" system but that is another issue. First of all, I want to be sure we are on the same sheet of music. I would like to suggest another option you may want to take a look at. ![]()
