The best shop especially for Cedar Creek would be Amish Family RV Service in Topeka In. Orvan was a Creek employee for a lot of years and is commonly referred to as the Cedar Creek "Guro". They are very popular and book out many months ahead, (260) 593-0951
You might also try the service center at the Shipshewana Flea Market and Campground, Ryan and his crew are also very good, we have used both shops and are pleased with their work.
