Took a while to comment because we have only had the Trail Air pin box and center point installed for about 6 weeks now and wanted to give them a true test before commenting. After 6 weeks and over 7,000 miles I am convinced that they are worth the money not due to the ride but because of the wear and tear on the trailer and truck. Bumps and pot holes are taken without the strain and twisting of the trailer frame as in before installing them and because there is less bump on the trailer things ride much better and we can leave more items out then ever before and our trailer already had a good suspension system on it. It took about two weeks of testing the air pressure in the bags to find the just right pressure and in the first few days the company changed the air bag in the pin box for me until we found the right combination. The people with Trail Air are easy and good to deal with and they really want the system to work, each time I called them they offered sugestions for new air pressures but always offered to buy the system back without cost to me if for any reason I was not happy with it. Now I would not give it back to them for double the money, that is not to say your results would be as good a mine, however have no reason to think they would not. Did learn that each trailer is a little different and to get the best combo you must be willing to experiment, on the other hand I know people that put it on and never had to change anything. Well worth the money for us, good luck to you if you go for it.
