To reply to Edgray's question, WRV products are now authorized to be serviced under warranty, or after, through the Cummins Coach Care system. Coach Care Service Centers can repair most items, and what they don't handle, they can refer to the nearest repair facility handling warranty or repairs for that component. There are approximately 30 service centers throughout the US, available 24/7 for emergency service. Check them out at http://www.Funroads.com/service
Also check out the new WRV Customer Service Facility in Yakima, WA at http://www.wrv.com/html/contact_service_center.html
WRV can also handle most every issue there, as well as offering phone support and service center referrals.
