happyjack2 - I didn't replace any tires. I exchanged the right front with the right rear inner tire. Then I replaced the front only shocks. The cupping did not re-occur on the one now on the right front and the right inner rear seemed to wear more even. The ride did not noticeably change.
PhilWH - Thanks for responding. The Model 211 was built on both the Ford and Chevy. We looked at those Sprinters and like them, but couldn't quite justify the difference in price. You've made the leap, you'll have to let us know if it was worth it.
