Might try the trail air Tri-glide. You get reduction in the up / down shock, AND the forward / aft shock. It's like combining a MorRyde with a standard trail air. I got one on order, and hopefully it will be in soon as the ridged pin box stinks.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
