We had problems with the ride height valves on our 2004 Country Coach Allure. We kept getting intermittent warning lights saying it wasn't at ride height. We took it to HWH in Moscow IA and it took them 4 days to find it. It was a valve that was sticking. We had them replace all 5 valves. Recently we had the back left side drop. We took it to Alliance Coach in Wildwood Florida and they found the dump valve to be defective. HWH is snowed under and won't call back right away. Their tech lines are very busy this time of year. It may take 2 weeks. Good news was while we were there they rebuilt the control box and updated the software which made it level much faster.
