Having had IS on two Montana’s now, and MorRyde pin boxes on three, and having been from Florida to Alaska and Texas to Maine, I feel I have some experience to share. I agree, IS is expensive. But, it makes a huge difference in the ride of the coach. We also put Timbren’s on the truck. I haven’t noticed a huge difference between the MorRyde pin box and the RotoFlex, but would prefer the MorRyde. Your hitch will also make a difference. We have a Pullrite 3900. Hitch also makes a difference in ride quality. John mentioned disc brakes. Our Legacy came with disc brakes and they transferred over with our IS install. If I prioritized my purchases it would be hitch, disc brakes, IS, Timbrens, pin box. Just my personal experience. YMMV.
