First post! Drove brand new Sightseer 37Z from Florida to Denver. Low pressure hose (rubber part) was vibrating against sharp point of chassis and wore a hole through it. Lost all refrigerant, so no AC. Under warranty from Ford, but now waiting for Ford to OK warranty work by shop in Denver. They said I should hear in 24 to 48 hours. So we are sitting and waiting. Had to use generator and cabin air to make it to Denver for daughter's wedding!
