OK, thank you all for your feed back, very much appreciated! I've done some research and have found some pretty good reviews on the cab-mate air system by Link. My particular application is just 735. for cab air ride, can also be purchased for your box or sleeper so is not to bolt directly to the frame. In addition a good pair of shocks and reducing tire air pressure may help as well. This truck does run, drive and brake very well, I think over time I will be able to get the ride to a tolerable level on mediocre roads and on nicely paved highway's a non issue, anyone know of any nicely paved highway's? Anyway, I will keep you posted of my progress, it will be slow but steady, pictures asap. Here is a link to link
