We have an 05 Cruise Master LE. The connections are inside and under the rig. There is a storage tube under the MH. Right now I've got the sewer hose in the storage tube and have it run up to the inside and connected to the drain outlet. There is a big bend in the hose at the connection. The owners manual only says that the tube is for storage. When we got the unit I ran the hose out of the storage bay to the outside hook-up. What do you do?
