I had the ole standard axle system with a rear kitchen 5th wheel and boy did we have trouble keeping things where they belong after a few hundred miles, so I made the drive OKC to MorRydes factory in Goshen and had the ole suspension system rip out and install the Independent system and WOW what a difference!!! No more mess in the 5er. Left there plant and traveled in Canada and down to the outer Banks then back to OKC and no problem. That was 4 years ago and we have traveled many miles since in all kinds of conditions and nothing but superb performance from the system. Well worth the money. I also added the MorRyde hitch pin too, again another MorRyde product worth the money.
