'98 Roadtrek 190P Changing out the big blue sewer hose

The different years changed slightly, but are basically the same. Take some photos before you take it apart. You may need to get a different drive, and extensions to get to the square headed screws. It's not a hard job, but not the most fun. Replace the hose with a heavy duty one, cut to fit the tube. I would get new clamps, and wrap the area where the clamps go over the hose with black electrical tape, to prevent them cutting into the hose.
